IKVM.NET - Java for Mono and .NET Framework
IKVM.NET is an implementation of Java for Mono and the Microsoft .NET Framework. It has JVM implemented in .NET. A .NET implementation of Java class libraries. It is interoperable between Java and .NET.
IKVM.NET includes ikvmc, a Java bytecode to .NET IL translator. If you have a Java library that you would like to use in a .NET application, run ikvmc -target:library mylib.jar to create mylib.dll.
IKVM provides a way for you to develop .NET applications in Java. Although IKVM.NET does not include a Java compiler for .NET, you can use any Java compiler to compile Java source code to JVM bytecode, then use ikvmc -target:exe myapp.jar to produce a .NET executable. You can even use .NET API's in your Java code using the included ikvmstub application.

cacaovm is a Java Virtual Machine (JVM) which uses Just-In-Time (JIT) compilation to execute Java methods natively. cacaovm uses GNU Classpath or OpenJDK or phoneME as Java runtime library. The cacaovm project started as a research JVM to explore new implementation techniques. The first version for the Alpha was released in February 1997 as a binary.
JC Virtual machine converts Java class files to C source code. It could also compiles with GCC and loads them with built-in ELF loader. Additional to that, JC provides a complete Java runtime with optimization to increase performance.
GNU Classpath provides core class libraries for use with virtual machines and compilers for the java programming language. GNU Classpath 1.0 will be fully compatible with the 1.1 and 1.2 API specifications, in addition to having significant compatibility with the 1.3, 1.4, 1.5 and 1.6 APIs.
Apache Harmony is a modular Java runtime with class libraries and associated tools. One of the goals of the Harmony project is to create a design modular enough so that parts of the VM can be implemented in different languages. This project started in 2005 and it is under active development.
Java Standard Edition provides Java development kit and Runtime to develop and deploy Java programs. Developed by Sun and take over by Oracle. It has support for different environments like Desktop, Embedded, Web, Realtime etc.
The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine. It is faster and more reliable than direct communication via the Java Native Interface, and it requires no additional components to invoke Java procedures from PHP or PHP procedures from Java.
What is it? Like JVM, It's a virtual machine. It has a set of bytecode. What special is it? The vm is designed for multi-thread in nature. It has no stack or registers. and every instrument is an atomic operation. so it cost nothing when context switching. How fast is it? Well, it is about 20x - 100x times slower than Java JVM or C on x86. It is reasonable for interpreted ones. I is an experimental VM just for my joy and curious. there is a benchmark What plan is it in the future? It was done, a
