Kaffe - Not Java
Kaffe is a clean room implementation of the Java virtual machine, plus the associated class libraries needed to provide a Java runtime environment. It has support for Garbage Collector, Debugging, Profiler, Benchmarking etc. It has been ported to multiple platforms. Among the open source VM, Kaffe is actively developed. Kaffe is not an officially licensed version of the Java virtual machine. It contains no Sun source code and was developed without even looking at the Sun source code. Kaffe is a great choice as a base for virtual machine education and research.

Cacaovm - Just-In-Time (JIT) Compiler
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.

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.
PHP Java Bridge
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.
IzPack - Cross-platform Installer
IzPack is a one-stop solution for packaging, distributing and deploying applications. It is fully cross-platform and generates a single installer. As such, it is an alternative to native solutions such as platform-specific installers and package managers. IzPack-generated installers only require a Java virtual machine to run.
