If you are searching for a jni4net alternative, you probably already understand the appeal of jni4net. It promised a direct way to bridge Java and .NET without rewriting one side of the application. It used generated proxies, supported calls in both directions, and let teams experiment with JVM/CLR interoperability from ordinary Java and .NET code.

That idea is still useful. The problem is not that jni4net was conceptually wrong. The problem is that many production teams now need a bridge for modern Java, modern .NET, Linux, containers, cloud deployments, supportable tooling, and enterprise operations. That is a much bigger requirement than a legacy in-process Windows bridge.

The short answer: JNBridgePro is the stronger jni4net replacement for production Java/.NET interoperability. jni4net can still make sense for old Windows/.NET Framework prototypes or maintaining a legacy internal integration. But if the work matters in production, JNBridgePro gives you the maintained runtime support, deployment flexibility, proxy tooling, and commercial support path that jni4net no longer provides.

What jni4net did well

jni4net deserves a fair reading. It is not just a toy wrapper. The project describes itself as a “fast, object oriented, intraprocess bridge between JVM and CLR” and as a bidirectional bridge between Java and .NET (SourceForge, GitHub). The original design used generated proxies so .NET code could call Java classes and Java code could call .NET classes.

That proxy model is the right basic abstraction. Developers do not want every cross-runtime call to become raw JNI, P/Invoke, sockets, hand-written serialization, or a custom REST service. They want a Java object or a .NET object to appear in the other runtime in a usable way.

For constrained cases, jni4net may still be adequate:

• a small Windows-only internal tool;
• an old .NET Framework application that already uses it;
• a prototype where open-source/no-license-cost matters more than supportability;
• a local in-process scenario with a narrow Java/.NET boundary;
• a legacy maintenance task where replacing the bridge would cost more than leaving it alone.

If that is your situation, the best answer may be to stabilize the existing code and avoid unnecessary migration.

But most teams searching for a modern alternative to jni4net are not trying to preserve a 2014-era experiment. They are trying to move a real integration forward.

Where jni4net becomes risky

The most important jni4net risk is project vitality. Public project pages show the latest GitHub release as 0.8.8.0 from September 2014, and SourceForge also shows 2014-era project activity (GitHub releases, SourceForge). The README and build notes reference older assumptions such as .NET SDK 3.5/4.0 and JDK 1.5, and the README states that Linux/Mono was not supported at the time (GitHub).

That does not mean every jni4net installation stops working. It means the risk shifts to your team. If you need to run on a newer JDK, move to .NET 8, deploy on Linux, containerize the Java side, debug native DLL loading, or satisfy enterprise support requirements, you should assume you will own a lot of that engineering burden yourself.

A production bridge is not just a library. It becomes part of your application’s runtime model. If the bridge is stale, every upgrade becomes harder:

• Which JDK versions are safe?
• Which .NET versions are supported?
• Can the bridge run outside Windows?
• Who fixes a native-loader bug?
• What happens when security or platform teams ask for vendor support?
• Can you isolate the JVM from the .NET process if reliability requires it?
• Can you run the Java side somewhere else on the network?

Those are not edge cases. They are normal production questions.

Why JNBridgePro is the production alternative

JNBridgePro approaches the same core problem — Java/.NET interoperability — as a maintained commercial product rather than a legacy open-source bridge. It uses generated proxies so Java and .NET classes can be used across runtime boundaries, while preserving the actual Java and .NET runtimes (How It Works).

The current JNBridgePro system requirements list .NET Framework 4.8 plus .NET 8, .NET 9, and .NET 10, along with JDK 8 through 25 on supported Windows and 64-bit Linux environments (System Requirements). That matters because many teams have exactly this problem: old .NET Framework code is still around, but new Java and .NET runtimes are entering the same architecture.

JNBridgePro also gives you deployment choices. It supports same-process, separate-process, and network deployment models, including on-premises, VM, container, and cloud scenarios (Overview, User Guide). That flexibility is a major difference from an in-process-focused bridge. If your first version can run locally but your production architecture later needs isolation, you have a path.

That is the real commercial jni4net alternative argument: not that jni4net never worked, but that JNBridgePro is built for the operational reality surrounding the bridge.

Benchmark evidence: production-shaped work favored JNBridgePro

Performance should be discussed carefully. The right claim is not “JNBridgePro is faster for every possible call.” In the May 22, 2026 benchmark, jni4net was faster on several local in-process microbenchmarks, including tiny repeated calls and bulk transfer rows.

The stronger production claim is more specific and more useful: JNBridgePro was about 3.15x faster than jni4net for a production-shaped batch workload where .NET crossed the bridge once and substantial Java code ran on a modern HotSpot JVM.

The checksums matched exactly, which means both bridges produced the same result for that workload. The key architectural point is that the JNBridgePro run used a modern JDK 25 JVM, while the jni4net run used Java 8. For a production integration, that is often exactly the point: Java remains Java, .NET crosses the bridge at a coarse boundary, and the Java side can run substantial computation on a current JVM.

This is how teams should design bridge integrations anyway. Avoid a million tiny cross-boundary calls. Batch work. Keep the runtime boundary coarse. Let Java do Java work and .NET do .NET work.

jni4net vs JNBridgePro decision table

Migration path from jni4net to JNBridgePro

A practical migration does not start by rewriting everything. Start by identifying the boundary:

1. List the Java classes or .NET classes currently exposed through jni4net proxies.
2. Separate chatty calls from coarse-grained business operations.
3. Move repeated tight-loop calls behind batch methods where possible.
4. Generate JNBridgePro proxies for the target classes.
5. Rebuild the integration using a topology that fits production: same process, separate process, or network.
6. Test behavior, exceptions, object lifetime, and performance under realistic workloads.

That approach lets you migrate the bridge without turning it into a full application rewrite.

FAQ

What is the best jni4net alternative?

For production Java/.NET interoperability, the best jni4net alternative is JNBridgePro. It is maintained, commercially supported, and currently lists support for modern .NET, modern Java, Windows, and 64-bit Linux.

Is jni4net still usable?

Yes, in some legacy or constrained cases. It may still be reasonable for an existing Windows/.NET Framework application or a prototype. The risk is using it as the foundation for a new production integration.

Is JNBridgePro faster than jni4net?

Not for every possible call. In the May 22 benchmark, jni4net won several local in-process microbenchmarks. But JNBridgePro was about 3.15x faster on the production-shaped batch workload where .NET crossed the bridge once and substantial Java code ran on a modern JVM.

Does JNBridgePro replace jni4net directly?

It replaces the role of jni4net — bridging Java and .NET — but the migration is not a drop-in binary swap. You should regenerate proxies, review runtime topology, and reshape chatty calls into coarse-grained calls.

Next step

If your jni4net use case is still small, local, and legacy, you may not need to move immediately. But if your team needs a supported production bridge for modern Java and .NET, start with the JNBridgePro overview, the How It Works page, and the JNBridgePro download.

If you are searching for an IKVM application server strategy, the real question is probably not “Can I convert this JAR?” It is “Can my .NET systems safely work with enterprise Java code that lives behind WebLogic, WebSphere, JBoss, WildFly, JMS, EJB, JNDI, and the operational rules that come with them?”

Short answer: IKVM can be useful when a .NET application needs to run a simple Java SE library inside the .NET runtime model. But enterprise Java is usually not just a library. It is a runtime environment, a container, a naming model, a transaction model, a messaging model, a security model, and a deployment topology. For that world, JNBridgePro is the stronger and more natural architecture.

IKVM’s own project description is clear: IKVM is a Java Virtual Machine and bytecode-to-IL converter for .NET. It can execute Java bytecode on .NET and can statically compile Java classes and JARs into .NET assemblies. That is valuable technology. But it is a Java-on-.NET compatibility approach, not a Java EE or Jakarta EE integration platform.

JNBridgePro takes a different path. It connects Java and .NET while allowing each side to remain itself. Java can run on a real JVM. .NET can run on .NET. The two sides communicate through generated proxies, with deployment choices that include same-process, cross-process, and networked scenarios. For enterprise architects dealing with WebLogic, WebSphere, JBoss, WildFly, JMS, EJB, and JNDI, that distinction matters.

Where IKVM can fit

IKVM deserves a fair place in the decision process. If your .NET team has a Java utility library, the library targets Java SE 8, the dependency graph is manageable, and the goal is to make that Java code look and behave like .NET code, IKVM may be a practical option.

The IKVM documentation and GitHub project describe a model built around running compiled Java bytecode on .NET, including static compilation into .NET assemblies and dynamic execution of Java bytecode from class files or JARs. IKVM also supports modern .NET versions, including .NET 6+, so it should not be dismissed as only a legacy .NET Framework tool.

That said, IKVM’s own support framing is important: IKVM targets Java SE 8 and provides a JRE/JDK 8 runtime image. Java SE 8 is not the same thing as Java EE or Jakarta EE. It is not WebLogic. It is not WebSphere. It is not a full application-server-resident system with container-managed services.

That is the point where an IKVM WebLogic, IKVM WebSphere, IKVM JBoss, or IKVM WildFly evaluation often becomes less about syntax and more about architecture.

Enterprise Java is not just bytecode

Enterprise Java applications are rarely self-contained JARs with a clean, static boundary. They often assume services supplied by an application server or enterprise runtime:

• JNDI naming and lookup
• JMS queues, topics, connection factories, and message-driven workflows
• EJB session beans, remote interfaces, transactions, and security context
• Container-managed resources
• Classloader behavior specific to an application server
• Deployment descriptors and server configuration
• Vendor-specific operational behavior in WebLogic, WebSphere, JBoss, or WildFly

That is why IKVM JMS, IKVM EJB, and IKVM JNDI are high-risk search paths for production architecture. The question is not whether some classes can be converted or executed. The question is whether the integration strategy respects the runtime assumptions of enterprise Java.

If a Java facade is meant to live inside WebLogic, WebSphere, JBoss, or WildFly, the safer architecture is usually to leave it there and expose a controlled bridge to .NET. That preserves the Java-side environment instead of trying to collapse the enterprise Java runtime into the .NET process.

The JNBridgePro model: integrate with enterprise Java, do not flatten it

JNBridgePro is built for Java/.NET interoperability rather than bytecode conversion. Its core promise is direct connection between “anything Java” and “anything .NET,” including modern .NET and Java environments. The important part for enterprise Java is that the Java side can remain Java.

The JNBridgePro How It Works page explains the proxy model: JNBridgePro generates proxies that expose APIs across the Java/.NET boundary and manage communication between Java and .NET classes. .NET code can call Java. Java code can call .NET. Calls can be bidirectional. The generated proxies make the foreign-side types feel usable without forcing the underlying runtime to be converted into something it is not.

For Java EE .NET integration and Jakarta EE .NET integration, that proxy-based approach is exactly what enterprise architects usually want. You can design an app-server-resident Java facade that speaks the application server’s language internally, then expose a cleaner interface to .NET through generated proxies.

A typical pattern looks like this:

1. Keep enterprise Java logic close to the app server, JVM, and container services it already depends on. 2. Create a Java facade with a stable API for .NET consumers. 3. Let that facade handle WebLogic, WebSphere, JBoss, WildFly, JMS, EJB, JNDI, transactions, and vendor-specific behavior internally. 4. Use JNBridgePro-generated proxies so .NET callers can invoke the facade without becoming responsible for the enterprise Java runtime.

That is a cleaner separation of responsibilities. .NET does not need to pretend to be an application server. Java does not need to stop being Java.

Why topology matters in application-server integration

Application-server integration is often decided by topology, not by a single API call. Where does the Java code run? Where does the .NET code run? What has to be isolated? What must stay in-process for latency? What must cross a machine boundary? What happens when the app server is managed by a separate operations team?

IKVM’s documented model centers on Java bytecode running within the .NET runtime model. That can be attractive for simple library reuse, but it is not the same as choosing among deployment topologies for a production Java/.NET bridge.

JNBridgePro explicitly supports a broader set of deployment choices. The JNBridgePro overview describes Java and .NET running in the same process, in different processes, or across a network. Its system requirements also show support for current .NET and Java environments, including Java versions well beyond Java 8.

That flexibility is useful in enterprise Java scenarios:

• Same-process deployment can reduce overhead when Java and .NET components are controlled together.
• Cross-process deployment can isolate runtimes while keeping communication efficient.
• Network deployment can support app-server, cloud, or separately managed enterprise environments.
• Java-side deployment can preserve real JVM behavior, app-server configuration, and vendor-certified stacks.

For a serious IKVM application server evaluation, this is the architectural fork in the road. Do you want to convert Java into the .NET world, or connect the Java and .NET worlds while preserving both?

WebLogic, WebSphere, JBoss, and WildFly scenarios

Consider a WebLogic or WebSphere deployment where Java code depends on JNDI lookups, JMS resources, EJBs, or server-managed transactions. A .NET application may need access to the business capability, but it should not necessarily inherit every Java-side complexity.

With JNBridgePro, the Java team can expose a facade that already knows how to find server resources, invoke EJBs, publish or consume JMS messages, and respect the application server’s security and transaction boundaries. The .NET team consumes the proxy surface. The integration boundary is explicit.

The same principle applies to JBoss and WildFly. If the Java code belongs in an application server, keep the Java-side integration point in the application server’s world. Use generated proxies to make that capability available to .NET callers. This is especially important when the Java application is not a greenfield library but an existing enterprise system with deployment history, operational constraints, and vendor-specific configuration.

That is the practical answer to searches like IKVM WebLogic, IKVM WebSphere, IKVM JBoss, and IKVM WildFly: the higher-value move is usually not to force the application-server model through IKVM. It is to bridge .NET to a Java facade that can safely live where the enterprise Java assumptions are true.

JMS, EJB, and JNDI: bridge the capability, not the container

The same logic applies at the service level.

For IKVM JMS, ask whether .NET really needs to host or reinterpret the Java messaging environment, or whether it needs to call Java code that already understands the JMS provider, connection factory, queues, topics, credentials, and transaction expectations.

For IKVM EJB, ask whether the target is simply a class or an enterprise component with container-managed behavior. If it is the latter, a bridge to a Java-side facade is a cleaner architecture than trying to pull that model into .NET.

For IKVM JNDI, ask where naming context should live. JNDI often reflects the deployed Java environment. A Java facade running in the right JVM or app-server context can perform those lookups naturally, then present a stable API to .NET.

This is where JNBridgePro’s bidirectional model becomes useful. Enterprise integration is not always .NET calling Java. Sometimes Java needs to call .NET services, callbacks, rules engines, reporting components, or user-interface layers. JNBridgePro is designed for both directions. IKVM’s conversion direction is Java-to-.NET; the IKVM README itself notes that it is not a tool for running .NET code in a normal JVM environment and that IKVM conversions are Java to .NET.

Decision table: IKVM vs JNBridgePro for enterprise Java

The decision is not “IKVM bad, JNBridgePro good” in every possible case. The better rule is this: use IKVM when the Java problem is truly a Java SE library conversion problem. Use JNBridgePro when the Java problem is an enterprise integration problem.

What benchmark evidence can and cannot prove here

Performance matters, but benchmark evidence should be used carefully for application-server decisions. A benchmark that compares IKVM and JNBridgePro on production-shaped Java/.NET calls does not prove WebLogic, WebSphere, JMS, EJB, or JNDI behavior by itself.

What it can support is the runtime-shape argument. In Max’s benchmark examples, JNBridgePro outperformed IKVM in production-shaped batch scenarios, including a coarse-grained risk aggregation case where JNBridgePro shared-memory completed the batch call in 3,530.875 ms versus IKVM at 12,185.226 ms, about 3.45x faster. In the matched-bytecode Monte Carlo VaR runs, JNBridgePro also won the larger production-shaped batch cases.

That evidence is relevant because enterprise Java integrations should usually be coarse-grained. You do not want a chatty boundary with thousands of tiny cross-runtime calls. You want a Java facade that performs meaningful work close to the Java runtime, then returns useful results to .NET. That is the same shape that favors a serious bridge architecture.

The benchmark does not replace an app-server proof of concept. It does strengthen the broader point: preserving the Java runtime model can matter for production behavior, not just compatibility.

Recommended architecture for enterprise teams

For most enterprise teams, the cleanest pattern is:

• Keep WebLogic, WebSphere, JBoss, WildFly, JMS, EJB, and JNDI concerns on the Java side.
• Create coarse-grained Java facades designed for .NET consumption.
• Use JNBridgePro-generated proxies to call those facades from .NET.
• Choose same-process, cross-process, or network deployment based on latency, isolation, operations, and ownership boundaries.
• Avoid making .NET responsible for Java container details it should not own.

That approach is easier to reason about, easier to operate, and easier to defend in architecture review. It lets enterprise Java remain enterprise Java while giving .NET applications direct access to the capabilities they need.

If you are still in the broader IKVM evaluation phase, start with the pillar comparison, IKVM Alternative: Why JNBridgePro Is Better for Production Java/.NET Interoperability. For the core architecture difference, read IKVM vs JNBridgePro: Bytecode-to-IL Conversion or True Java/.NET Bridging?. If your team began with JAR conversion, see IKVM JAR to DLL Alternative: Use a Java JAR in .NET Without Converting the Runtime. And if Java version support is part of the risk analysis, read IKVM Java 8 Limitation: A Modern Java Alternative for Java 11, 17, and 21.

For enterprise Java, the conclusion is straightforward: IKVM can be useful for Java SE 8 library compatibility, but an application server is not just a library. When your .NET systems need to work with real JVMs, generated proxies, bidirectional calls, WebLogic, WebSphere, JBoss, WildFly, JMS, EJB, JNDI, Java EE, or Jakarta EE, JNBridgePro is the safer production architecture.

If you are searching for IKVM Maven dependencies, there is a good chance you are not doing casual research. You are probably trying to make a real Java library work inside a .NET build, and the dependency graph is starting to fight back.

That is where IKVM can become complicated. IKVM is useful when a Java library is simple, Java SE 8-compatible, and dependency-light. It can execute Java bytecode on .NET and statically compile Java libraries into .NET assemblies. For small utility JARs, that model can be convenient.

But Maven dependency graphs are rarely just one JAR. A production Java library may bring dozens or hundreds of artifacts, optional dependencies, classifiers, generated code, service loaders, reflection-heavy frameworks, runtime resources, version constraints, and transitive dependencies that were designed to resolve inside the Java ecosystem. When those artifacts are converted into .NET build artifacts, the integration problem changes shape.

The short answer: IKVM Maven dependencies can work for simple Java SE 8 libraries, but they can create build and maintenance risk when the Java dependency graph is large, transitive, dynamic, or tied to modern Java. JNBridgePro avoids much of that risk by keeping Java artifacts as Java artifacts and connecting .NET to Java through generated proxies.

That difference is the core architectural issue. IKVM converts Java bytecode into the .NET world. JNBridgePro connects the Java and .NET worlds without forcing either side to stop being itself.

What IKVM does well with Java libraries

IKVM deserves credit for solving a real problem. The IKVM GitHub project describes IKVM as “a Java Virtual Machine and Bytecode-to-IL Converter for .NET.” Its documentation explains that IKVM can run Java bytecode on .NET and can statically compile Java classes or JARs into .NET assemblies.

That can be attractive when a .NET team wants to use a Java library without operating a separate JVM. If the Java library is small, stable, compatible with Java SE 8, and has a clean dependency set, IKVM may be a reasonable engineering choice.

For example, IKVM can fit scenarios like:

• a self-contained Java utility library;
• a Java SE 8-era dependency with limited external references;
• a library that does not depend heavily on reflection, dynamic class loading, native code, app servers, or modern Java APIs;
• a .NET application where packaging everything into the .NET runtime model is more important than preserving real JVM behavior.

That is the best version of the IKVM story. It can reduce moving parts for simple Java-on-.NET use cases.

The trouble starts when the Java library is not simple.

Why Maven dependency graphs are different from single-JAR conversion

A Maven dependency is not just a downloadable file. It is part of a dependency resolution system.

In normal Java development, Maven coordinates artifact versions, scopes, exclusions, optional dependencies, repositories, transitive dependencies, and classpaths. The Java runtime then loads classes and resources according to the application’s classpath, module path, framework behavior, or application-server environment.

When you use IKVM, the integration model is different. IKVM is not merely “point .NET at Maven and let Java run normally.” IKVM’s model brings Java bytecode into .NET through runtime execution or static compilation. That means the Java dependency graph can become part of the .NET build and assembly-reference problem.

This is not just theoretical. The IKVM.Maven GitHub project notes that underspecified Maven dependencies can be a problem because IKVM is statically compiling assemblies and needs to track dependencies between assemblies. It explains that IKVM cannot fully build one library if it depends on missing classes from another library.

That is the build-risk issue in plain English: a Maven graph that is acceptable in Java can become fragile when every relevant artifact needs to be understood, compiled, referenced, and maintained as part of a .NET assembly graph.

For a small dependency tree, that may be manageable. For a large dependency tree, it can become a recurring source of failed builds, missing classes, version conflicts, and hard-to-debug runtime behavior.

The transitive dependency trap

The phrase IKVM transitive dependencies is important because many teams expect Java dependency behavior to carry over automatically.

In Java, if Library A depends on Library B, Maven normally resolves that relationship for the consuming application unless scope, optional flags, exclusions, or version mediation change the result. Developers still need to manage dependencies carefully, but Maven’s default model is built around transitive resolution.

IKVM’s .NET build model does not map perfectly to that expectation. The IKVM README states that IkvmReference is not transitive: a project that depends on another project with an IkvmReference does not automatically receive that same reference. The consuming project may need the IKVM reference added again.

That can surprise teams. A dependency that feels “already included” in the Java mental model may need explicit handling in the .NET project model. As the number of Java dependencies grows, the number of places where transitive assumptions can break grows with it.

This is the risk:

• the Java project builds correctly in Maven;
• the .NET project compiles only after additional IKVM references are declared;
• a downstream .NET project fails because a reference was not transitive;
• a library upgrade changes the graph and reopens the problem;
• the team spends integration time managing converted artifacts instead of shipping product functionality.

That does not make IKVM bad. It means IKVM is strongest when the dependency graph is small enough that the conversion model remains easy to reason about.

Dynamic class loading and reflection raise the stakes

Dependency graphs are not always visible at compile time. Many Java libraries discover classes dynamically.

That is why searches like IKVM dynamic class loading and IKVM reflection support often come from frustrated integration work. A Java library may appear to compile, only to fail when a framework tries to load a class by name, discover an implementation through a service descriptor, inspect annotations, generate proxies, or invoke behavior reflectively.

Java frameworks commonly use:

• Class.forName() and custom class loaders;
• ServiceLoader provider discovery;
• annotation scanning;
• bytecode generation;
• reflection-based serializers and mappers;
• plugin architectures;
• runtime resource loading;
• container-managed lifecycle behavior.

Those patterns assume Java is running as Java. They assume normal JVM class loading, Java resources, classpath conventions, and framework expectations.

IKVM can support Java bytecode execution in many cases, but its architectural premise is still Java running inside the .NET runtime model. When a dependency relies on dynamic runtime behavior rather than a clean static API surface, the integration becomes harder to validate. The build may not reveal every problem. Some failures only appear under production paths, specific configurations, or rarely used plugins.

JNBridgePro approaches this differently. According to the JNBridgePro How It Works documentation, JNBridgePro generates proxies that expose APIs and manage communication between Java and .NET classes. Java code continues to run on the Java side. .NET calls Java through the bridge.

That matters because Java dependencies remain Java dependencies. You are not asking every Java artifact to become a .NET assembly. You are preserving the runtime environment that the Java code was built and tested for.

Modern Java makes the conversion question more expensive

Another common search pattern is IKVM not working with Java 17. That usually signals a deeper mismatch than one missing class or one broken dependency.

IKVM’s own project documentation describes support for Java SE 8 and a JRE/JDK 8 runtime image. IKVM also supports modern .NET, including .NET 6+, but modern .NET support is not the same thing as modern Java support. If the Java dependency was built for Java 11, Java 17, Java 21, or newer, the central question is whether converting it into the IKVM model is a good long-term strategy.

Modern Java libraries may depend on newer standard-library APIs, module-era assumptions, updated TLS/security behavior, newer bytecode, newer build plugins, or vendor support policies tied to current JDKs. Even when a library can be compiled or adapted, the maintenance question remains: do you want your Java/.NET integration strategy tied to a Java SE 8 compatibility layer?

JNBridgePro is stronger here because it keeps Java on a real JVM. The JNBridgePro system requirements currently list Java-side support for JDK versions 8 through 25. That gives teams a clearer path when Java dependencies move forward.

This is not a minor distinction. Many dependency problems are version problems wearing a different costume. If the Java ecosystem around you is moving to Java 17 or Java 21, an integration model centered on Java SE 8 compatibility can become a strategic liability.

For more detail on that version issue, see the campaign article on the IKVM Java 8 limitation. For the broader comparison, start with IKVM Alternative: Why JNBridgePro Is Better for Production Java/.NET Interoperability and IKVM vs JNBridgePro: Bytecode-to-IL Conversion or True Java/.NET Bridging?.

JNBridgePro keeps Java artifacts as Java artifacts

The cleanest way to understand the JNBridgePro advantage is this: JNBridgePro does not require your Java dependency graph to become a .NET dependency graph.

With JNBridgePro, Java runs on the JVM. .NET runs on .NET. Generated proxies provide the callable surface between the two sides. JNBridge describes JNBridgePro as connecting “anything Java” with “anything .NET,” including deployment in the same process, in different processes, or across a network. It also supports Windows and Linux deployment options (JNBridgePro overview).

That architecture changes the dependency-management conversation.

Instead of asking:

• Can every Maven artifact be converted successfully?
• Are all transitive references represented correctly in the .NET project?
• Will a downstream .NET project inherit the Java references I expect?
• Will static compilation catch every dynamic class-loading path?
• Will a Java 17-oriented dependency fit a Java SE 8 compatibility target?

You can ask:

• Which Java APIs should .NET call?
• Which side should own object creation and lifecycle?
• Should the bridge run in-process, cross-process, or over the network?
• Which JDK should the Java side use?
• Which proxy surface gives .NET the cleanest integration point?

That is a better set of production questions.

It is also more aligned with how enterprise systems actually evolve. Java teams can update Java artifacts in the Java environment. .NET teams can update .NET code in the .NET environment. The bridge connects the two without forcing both ecosystems into one build artifact model.

Practical decision table

The point is not that every IKVM project will fail. The point is that the risk profile changes as the Java side becomes more realistic. The more your Java dependency graph looks like production Java, the more valuable it becomes to keep Java running as Java.

What the benchmark context does and does not prove

The current campaign benchmarks are useful, but they should not be overstated for this specific topic. They do not prove that JNBridgePro resolves every Maven graph more easily than IKVM in every case. They do not benchmark Spring Boot, Hibernate, Java EE, or a dependency-heavy Maven application.

What they do support is the broader runtime-model argument. In production-shaped batch scenarios from the campaign benchmark suite, JNBridgePro performed better than IKVM while preserving real JVM execution. The strongest matched-bytecode runs used the same Java source compiled once for both sides, making the runtime model itself part of the explanation.

For this article, the relevant lesson is not “benchmarks prove Maven dependency handling.” They do not. The relevant lesson is simpler: the runtime model matters. If performance, compatibility, and long-term maintainability depend on Java behaving like Java, then preserving a real JVM is a serious architectural advantage.

The dependency argument stands on its own: IKVM turns Java dependencies into .NET build artifacts; JNBridgePro lets Java dependencies remain Java artifacts and connects to them through proxies.

The safer production choice

If your project is small, Java SE 8-compatible, and dependency-light, IKVM may be a practical way to bring Java code into .NET. It is a legitimate tool for that use case.

But if you are already searching for IKVM Maven dependencies, IKVM transitive dependencies, IKVM dynamic class loading, IKVM reflection support, or IKVM not working with Java 17, you may have outgrown the simple-case version of the problem.

At that point, the better question is not “how do we force this Java graph into .NET?”

The better question is: why not let Java stay Java?

JNBridgePro is built for that answer. It keeps Java on a real JVM, keeps .NET on .NET, exposes Java and .NET APIs through generated proxies, supports bidirectional calls, and gives teams deployment choices across same-process, cross-process, and network configurations. For production Java/.NET integration, that is a cleaner and more durable architecture than converting a complex Maven world into a .NET assembly world.

If you are evaluating IKVM because you need a quick way to use a simple Java library from .NET, test it. If you are evaluating IKVM because a production Java dependency graph is already creating build risk, start with JNBridgePro, review how JNBridgePro works, and confirm your platform fit in the system requirements.

For teams that need Java/.NET interoperability without turning Java into a converted build problem, JNBridgePro is the stronger production path.

If you are searching for IKVM JAR to DLL, you probably have a practical problem: you have a Java library packaged as a JAR, and you need to use it from a .NET or C# application.

The tempting answer is obvious: convert the JAR into a DLL, reference it from Visual Studio, and call it like any other .NET assembly.

That can be a good idea for some projects. IKVM is designed for exactly this kind of Java-on-.NET compatibility work. The current IKVM project describes itself as “a Java Virtual Machine and Bytecode-to-IL Converter for .NET,” and the IKVM site explains that it can execute Java bytecode on .NET and statically compile Java libraries into .NET assemblies. That makes IKVM a natural result when developers search for IKVM convert JAR to DLL, “convert Java JAR to .NET DLL,” or use Java library in C#.

But converting a JAR into a DLL is not the only way to use a Java JAR in .NET. For production systems, it is often not the safest way.

JNBridgePro takes a different approach. Instead of translating Java bytecode into the .NET runtime model, JNBridgePro lets .NET call Java while Java stays Java, running on a real JVM. It generates proxies that expose Java APIs to .NET, manages the communication between runtimes, and supports same-process, cross-process, and network deployment options.

The short version:

IKVM converts Java into the .NET world. JNBridgePro connects the Java and .NET worlds without forcing either one to stop being itself.

If your goal is a quick proof of concept with a simple Java SE 8 library, IKVM may be enough. If your goal is a production .NET application that needs to run a Java JAR from C#, preserve JVM behavior, use modern Java, or keep deployment options open, JNBridgePro is usually the stronger architecture.

Why developers want to convert a JAR to a DLL

The appeal of JAR-to-DLL conversion is easy to understand.

A .NET developer wants to:

• reference the Java library from a C# project;
• call Java classes using familiar .NET tooling;
• package everything into a .NET deployment;
• avoid running a separate Java service;
• avoid rewriting a working Java library in C#.

From that perspective, an IKVM JAR to DLL workflow sounds elegant. Take the Java artifact, convert it into a .NET assembly, add a reference, and move on.

For small libraries, stable APIs, and Java SE 8-compatible code, that model can be useful. IKVM’s project documentation says IKVM can run compiled Java bytecode on .NET Framework or .NET Core and can compile Java classes and JARs into .NET assemblies. IKVM also supports .NET Framework 4.7.2+ and .NET 6+, so it is not simply an old .NET Framework-only tool.

The question is whether that is what your production application really needs.

What changes when you convert Java into .NET

A JAR is not just a file full of methods. It is an artifact built for the Java runtime model.

Java libraries may depend on:

• JVM class loading behavior;
• Java reflection conventions;
• Java threading and memory behavior;
• Java security and resource-loading assumptions;
• JDK class libraries;
• native libraries through JNI;
• framework behavior from Maven dependency graphs;
• modern JDK features beyond Java 8.

When you convert a JAR to a DLL, you are changing more than the file extension. You are moving Java bytecode into a different runtime model.

That may be acceptable for a simple utility library. It becomes more sensitive when the Java library is large, dependency-heavy, performance-critical, or designed around real JVM behavior.

IKVM’s README is clear that its conversion direction is Java to .NET, not .NET running inside a normal Java environment: “all IKVM conversions are Java > .NET.” It also documents Java SE 8 support and a JRE/JDK 8 runtime image. That makes it a practical Java-on-.NET compatibility layer, but not the same thing as running your Java library on HotSpot, OpenJDK, or the JVM version your Java team already tests against.

That is the key architectural tradeoff.

With IKVM, the .NET side becomes the runtime home for translated Java.

With JNBridgePro, Java stays on the JVM and .NET stays on the CLR.

JNBridgePro: use the Java JAR from .NET without turning it into a DLL

JNBridgePro is built for Java/.NET interoperability rather than bytecode conversion.

The JNBridgePro overview describes it as connecting “anything Java” with “anything .NET,” including .NET Framework and .NET Core/.NET, and supporting deployments in the same process, different processes, or across a network. Its How It Works documentation explains that JNBridgePro generates proxies that expose APIs and manage communication between Java and .NET classes.

For a C# developer, that means you can call Java classes through .NET-facing proxies. But the Java implementation remains Java. The JAR is loaded by a JVM. The Java code runs as Java code. The .NET code calls into it through the bridge.

That difference matters when you need to use a Java library in C# but do not want to take ownership of a translated runtime artifact.

Instead of asking, “How do I convert this JAR to a DLL?” the production question becomes:

“How do I call this Java library from .NET while preserving the runtime behavior it was built for?”

JNBridgePro’s answer is: generate proxies, keep both runtimes, and choose the deployment model that fits the application.

Why “Java stays Java” is safer for production

JAR-to-DLL conversion can feel simpler at the beginning. But production risk often appears later: when the Java dependency changes, when a new JDK matters, when performance depends on JIT behavior, when a framework expects JVM semantics, or when deployment topology changes.

Keeping Java on a real JVM gives you several practical advantages.

1. You preserve the runtime your Java code was built for

If a vendor ships a Java JAR, they usually test it on a JVM. If your internal Java team owns the library, they probably build and test it with Java tooling. JNBridgePro lets that Java artifact continue to run in its expected environment.

2. You are not boxed into Java SE 8 compatibility

IKVM targets Java SE 8. For some libraries, that is fine. For modern Java code, it can be a hard limit.

JNBridgePro’s system requirements list support for JDK versions 8 through 25 on the Java side, with .NET Framework 4.8 and modern .NET versions on the .NET side. If your Java library is already on a newer JDK, or if you expect it to move forward, a real-JVM bridge is a cleaner long-term fit.

3. You keep deployment flexibility

A converted DLL gives you one basic model: Java bytecode translated into the .NET application’s world.

JNBridgePro gives you more topology choices. You can run Java and .NET in the same process when that is appropriate. You can separate them into different processes for isolation. You can bridge across a network when the architecture calls for distributed deployment.

That flexibility matters in enterprise systems, where the first integration shape is rarely the last one.

4. You can support bidirectional interoperability

IKVM’s documented conversion direction is Java to .NET. JNBridgePro is designed for both directions: .NET can access Java, and Java can access .NET through generated proxies.

If your only need is “call this Java method from C#,” that may not matter today. But many real integrations become bidirectional over time.

5. You reduce build-artifact risk for complex dependencies

When you convert Java dependencies into .NET assemblies, the build pipeline must understand and preserve relationships that were originally designed for Java tooling.

IKVM.Maven’s README notes that underspecified Maven dependencies can be a problem because IKVM is statically compiling assemblies and needs to track dependencies between assemblies. IKVM’s README also says IkvmReference is not transitive, meaning downstream .NET projects may need to repeat references instead of automatically inheriting them.

For simple cases, that may be manageable. For larger dependency graphs, it is another reason to question whether conversion is the right production model.

JNBridgePro keeps Java artifacts as Java artifacts and uses proxies to connect the runtimes. That can reduce the maintenance risk of turning a Java dependency graph into a .NET assembly graph.

Performance: the runtime model can matter even with the same JAR

Performance should be tested with your own workload. No responsible vendor should claim one architecture is always faster in every possible call shape.

But the benchmark evidence for this campaign supports an important point: preserving the JVM can matter, especially for production-shaped work.

In a risk aggregation benchmark, JNBridgePro shared-memory completed the coarse-grained batch call in 3,530.875 ms, compared with IKVM at 12,185.226 ms — about 3.45x faster.

In the matched-bytecode Monte Carlo VaR run, the same Java source was compiled once with javac --release 8, and the same JAR was reused on both sides. That setup is useful because it reduces the “different Java artifact” objection. Even when the Java artifact was held constant, the runtime model still mattered.

In that matched-bytecode run, JNBridgePro was:

• 2.30x faster in batch sequential mode at N=50;
• 3.60x faster in batch sequential mode at N=200;
• 3.14x faster in batch parallel mode at N=200.

The right conclusion is not “JNBridgePro is always faster.” The defensible conclusion is stronger for production buyers: JNBridgePro was faster in benchmark scenarios that look like real integration work, where Java behaves like an engine and .NET calls it in coarse-grained batches.

That is exactly the kind of workload where converting Java into another runtime model can become less attractive.

Decision table: IKVM JAR to DLL vs JNBridgePro

When IKVM is the right first thing to try

This is not an argument that IKVM has no place.

IKVM may be a practical choice when:

• the Java library is small and stable;
• it targets Java SE 8-compatible APIs;
• you want a .NET assembly artifact;
• the library has limited external dependencies;
• you do not need modern JVM behavior;
• you do not need Java-to-.NET callbacks;
• you are building a prototype, internal utility, or low-risk integration.

For those cases, an IKVM convert JAR to DLL workflow can be attractive precisely because it collapses the problem into the .NET build.

But that same simplification can become the limitation.

If the Java code matters enough to be part of a production system, ask whether you really want to translate it away from the runtime it was designed for.

When JNBridgePro is the better production answer

JNBridgePro becomes the stronger choice when the Java library is not just a small utility, but a real dependency in your application architecture.

Choose JNBridgePro when you need to:

• run a Java JAR from C# without converting it into a .NET assembly;
• preserve real JVM execution and JIT behavior;
• use Java libraries built for newer JDKs;
• integrate .NET with Java frameworks or enterprise Java systems;
• support callbacks from Java into .NET;
• choose same-process, different-process, or network deployment;
• avoid turning Java dependency management into .NET assembly management;
• keep Java and .NET teams working in their native toolchains.

The better question: not “Can I convert it?” but “Should I?”

When developers search for IKVM JAR to DLL, they usually want a practical path from C# to Java. The phrase “convert JAR to DLL” is the search term, not necessarily the architectural requirement.

The real requirement is usually one of these:

• “I need to call a Java library from C#.”
• “I need to use a vendor’s Java SDK in a .NET application.”
• “I need to reuse Java code without rewriting it.”
• “I need Java and .NET to work together in production.”

For some of those, conversion is fine.

For many production systems, bridging is safer.

IKVM is a Java-on-.NET compatibility layer. JNBridgePro is a Java/.NET interoperability platform. If all you need is a converted assembly for a simple Java SE 8 library, IKVM may solve the problem. If you need the Java library to keep behaving like Java, JNBridgePro gives you the more durable path.

Next step: run your Java JAR from C# without converting the runtime

If you are evaluating an IKVM JAR to DLL approach, test the conversion path — but test the bridge path too.

JNBridgePro lets you call Java from .NET while keeping Java on a real JVM, preserving modern Java options, and choosing the deployment model that fits production instead of forcing the Java code into a converted DLL.

To see the production-oriented alternative, start with JNBridgePro’s pages for running a Java JAR from C# and calling Java from .NET.

If you are searching for an IKVM alternative, you probably already understand the appeal of IKVM. You have Java code, a .NET application, and a practical business need: make the two work together without rewriting everything.

IKVM can be useful for that. It is a Java Virtual Machine and bytecode-to-IL converter for .NET, and its own documentation describes support for executing Java bytecode on .NET Framework or .NET Core, including static compilation of Java libraries into .NET assemblies and dynamic execution from JAR or class files (IKVM, IKVM GitHub). For simple Java SE libraries that you want to pull into a .NET build, that model can be attractive.

But production Java/.NET integration often becomes more demanding than “turn this JAR into something .NET can call.” Teams need real JVM behavior. They need bidirectional calls. They need modern JDKs. They need app-server, enterprise Java, and deployment choices. They need performance that holds up when Java is doing meaningful work, not just utility-method calls.

That is where JNBridgePro is the stronger choice.

JNBridgePro is not another Java-to-.NET conversion tool. It is a Java/.NET interoperability platform that keeps Java on the JVM and .NET on the CLR, then connects the two using generated proxies and high-performance communication (JNBridgePro overview, How It Works). If IKVM converts Java into the .NET world, JNBridgePro connects the Java and .NET worlds without forcing either side to stop being itself.

Short answer: the best IKVM alternative for production is JNBridgePro

JNBridgePro is the better IKVM replacement when your integration needs to preserve Java runtime behavior, support modern Java, call in both directions, or deploy across same-process, cross-process, network, on-premises, cloud, Windows, or Linux environments.

IKVM is best understood as Java-on-.NET compatibility. JNBridgePro is production Java/.NET interoperability.

That architectural difference matters. IKVM’s own README states that its conversions are Java to .NET and that it is not a tool for running .NET code in Java (IKVM GitHub). JNBridgePro, by contrast, is explicitly built for Java-to-.NET and .NET-to-Java interoperability. Its generated proxies let .NET code access Java classes and Java code access .NET classes (How It Works).

So if your only goal is to bring a small Java SE 8 library into a .NET project, IKVM may be enough. If your goal is a durable production bridge between real Java and real .NET systems, JNBridgePro is the option designed for that job.

What IKVM does well

A fair comparison starts with the reason IKVM gets evaluated in the first place: it can be convenient.

IKVM can run compiled Java bytecode on .NET and can statically compile Java libraries and class files into .NET assemblies (IKVM). That makes it appealing when a .NET team has a Java library and wants to consume it through familiar .NET build and deployment patterns.

IKVM also supports modern .NET targets. The project lists support for .NET Framework 4.7.2+ and .NET 6+, and it supports multiple operating systems and architectures (IKVM GitHub). It is not accurate to dismiss IKVM as simply “old .NET only” or Windows-only.

For smaller Java SE 8-oriented libraries, especially libraries without complex runtime assumptions, that can be a workable approach. If your Java dependency is stable, simple, and mostly a set of pure Java functions, converting Java bytecode into the .NET runtime model may solve the immediate problem.

But that same model is also where the production tradeoffs begin.

Where IKVM becomes limiting

IKVM’s core promise is also its boundary: it moves Java bytecode into the .NET runtime model. That is very different from running Java on a standard HotSpot JVM.

IKVM’s project documentation describes it as implementing a JVM in .NET, implementing Java class libraries in .NET, and converting bytecode to CIL/IL (IKVM GitHub). That can be exactly what you want for compatibility scenarios. It is not the same thing as preserving the JVM as the Java runtime.

For production systems, that distinction can affect several areas.

Modern Java and JVM behavior

IKVM targets Java SE 8 and provides a JRE/JDK 8 runtime image (IKVM GitHub). Many production Java systems now depend on later Java language, library, JVM, and ecosystem behavior. Even when source compatibility is manageable, runtime behavior can matter: class loading, reflection, JIT behavior, tooling expectations, monitoring, and the broader Java library ecosystem are all shaped around a real JVM.

JNBridgePro is built around preserving that JVM. Current JNBridgePro system requirements list support for JDK versions 8 through 25, along with .NET Framework 4.8 and .NET 8, .NET 9, or .NET 10 on supported Windows and Linux environments (JNBridgePro system requirements).

That makes JNBridgePro a more natural path when your Java code is not frozen in a Java 8-shaped world.

Bidirectional interoperability

IKVM’s conversion direction is Java to .NET. Its README says all IKVM conversions are Java > .NET and that IKVM is not a tool for running .NET code in Java (IKVM GitHub).

That matters when the real requirement is not simply “call Java from C#.” Many production integrations need both sides to participate. A .NET application may call Java services, while Java code calls back into .NET business logic, UI, services, or infrastructure.

JNBridgePro is designed for that bidirectional model. It generates proxies that expose APIs across the Java/.NET boundary and manages communication between Java and .NET objects (How It Works). That is a fundamentally different value proposition from converting Java artifacts into .NET artifacts.

Enterprise Java and deployment topology

IKVM targets Java SE. JNBridgePro is positioned for broader enterprise interoperability, including Java EE and Jakarta EE scenarios, EJB, JMS, JNDI, and major application-server environments such as WebSphere, WebLogic, JBoss, and WildFly (JNBridgePro overview).

Deployment flexibility is another key difference. IKVM’s documented model is Java bytecode running or being compiled on .NET. JNBridgePro supports running Java and .NET in the same process, in different processes, or across a network, including on-premises and cloud deployments, on Windows or Linux (JNBridgePro overview).

That gives architects choices. If same-process performance is the priority, JNBridgePro can support that. If isolation matters, the Java and .NET sides can run in different processes. If distribution matters, they can communicate across a network. You are not locked into one runtime shape.

Java dependency management

IKVM can also introduce build-time complexity for larger Java dependency graphs. IKVM.Maven’s README notes that underspecified Maven dependencies can be a problem because IKVM statically compiles assemblies and must track dependencies between assemblies; it cannot fully build one library if it depends on missing classes from another (IKVM.Maven GitHub). IKVM’s README also notes that IkvmReference is not transitive and that projects depending on another project with an IkvmReference must add that reference again (IKVM GitHub).

JNBridgePro avoids turning Java dependency management into .NET assembly conversion. Java artifacts stay Java artifacts. .NET artifacts stay .NET artifacts. Proxies connect the runtimes. For complex systems, that can reduce build and maintenance risk.

JNBridgePro’s production advantage: preserve the JVM, preserve .NET

The simplest way to compare IKVM vs JNBridgePro is this:

• IKVM converts Java bytecode into the .NET execution model.
• JNBridgePro connects Java and .NET while preserving their native runtimes.

That preservation is the point. Java code continues to run on a JVM. .NET code continues to run on the CLR. Each side can use its normal tooling, runtime expectations, deployment model, and ecosystem.

JNBridgePro’s generated proxies give developers a natural way to access classes across the boundary, while JNBridgePro handles the communication layer (How It Works). Instead of forcing a Java library to become a .NET assembly, JNBridgePro lets Java remain Java and .NET remain .NET.

For production teams, that can mean less architectural compromise. You can modernize the .NET side without pretending Java is .NET. You can preserve Java behavior without rewriting the .NET application. You can place the Java and .NET components together or apart, depending on performance, security, operations, and deployment needs.

That is why JNBridgePro is not merely an IKVM.NET alternative. It is a different class of solution.

Performance evidence: production-shaped benchmarks favored JNBridgePro

Architecture matters, but performance matters too. In benchmark scenarios shaped around realistic production integration patterns, JNBridgePro showed a clear advantage over IKVM.

The most straightforward proof point came from a risk aggregation benchmark using a coarse-grained batch call. JNBridgePro shared-memory completed the batch call in 3,530.875 ms, while IKVM took 12,185.226 ms. That is about 3.45x faster for JNBridgePro in that production-shaped scenario.

A second expanded Monte Carlo VaR benchmark reinforced the same pattern. In a matched-bytecode rerun, the same Java source was compiled once with javac --release 8, and the same JAR was reused on both sides. That made the comparison more credible because the Java artifact was held constant. The remaining difference came from the runtime model: HotSpot JVM execution through JNBridgePro versus IKVM-translated Java running as MSIL.

In that matched-bytecode run, JNBridgePro’s advantage grew with workload size:

The largest matched-bytecode run showed JNBridgePro 3.60x faster than IKVM.

The right conclusion is not that JNBridgePro will be faster in every possible micro-scenario. No responsible vendor comparison should claim that. The useful production conclusion is stronger and more defensible: when Java behaved like a real engine doing meaningful batch work, JNBridgePro was faster in the benchmark scenarios that matter most for production integration.

That result supports the architectural argument. Preserving the JVM is not just a purity point. For meaningful Java workloads, running on the real JVM can deliver practical performance advantages.

There is a memory tradeoff. IKVM’s working set in the benchmark was 72.4 MiB, while JNBridgePro’s was 425.4 MiB, reflecting the embedded JVM heap configuration. That is the expected cost of running a real JVM. If the goal is the lightest possible footprint for a small Java SE 8 library, IKVM may be attractive. If the goal is production Java behavior, modern JVM support, and high-throughput batch integration, JNBridgePro gives you more of what production teams actually need.

IKVM vs JNBridge: practical decision table

This is the heart of the IKVM vs JNBridge decision. IKVM is appealing when the problem is narrow: “Can I make this Java library run in .NET?” JNBridgePro is compelling when the problem is strategic: “Can I integrate Java and .NET systems in production without compromising either platform?”

When to choose JNBridgePro as your IKVM replacement

Choose JNBridgePro when Java matters as Java.

That includes situations where your Java code depends on JVM behavior, modern JDK support, enterprise Java infrastructure, large dependency graphs, Java-side services, or deployment separation. It also includes performance-sensitive systems where the Java side is doing meaningful work and should be allowed to run on an optimized JVM.

Choose JNBridgePro when the relationship between Java and .NET is not one-way. If .NET calls Java today, but Java needs to call back into .NET tomorrow, you want an interoperability platform, not a one-direction conversion strategy.

Choose JNBridgePro when deployment flexibility matters. Same process, different processes, across a network, on-premises, cloud, Windows, Linux: those choices give architects room to build the right production topology instead of bending the architecture around a conversion tool.

And choose JNBridgePro when you want a solution that aligns with how enterprise systems are actually operated. Java teams can keep Java runtime assumptions. .NET teams can keep .NET runtime assumptions. Both sides can meet through a bridge built for that purpose.

The bottom line

IKVM has a place. It can be useful for simple Java SE 8 compatibility scenarios where the goal is to bring Java bytecode into a .NET application and keep the footprint light.

But if you are searching for an IKVM alternative because your requirements have moved beyond simple conversion, JNBridgePro is the stronger production choice. It preserves real JVM execution, supports bidirectional Java/.NET interoperability, offers flexible deployment models, supports modern Java and current .NET platforms, and showed meaningful performance advantages in production-shaped benchmark scenarios.

IKVM converts Java into the .NET world. JNBridgePro connects Java and .NET without forcing either one to give up what makes it valuable.
