What I currently have is:

• java/lang/Object to System.Object & java/lang/String to System.String mapping
• On demand class loading infrastructure (but no ClassLoader support)
• Code to read and parse Java .class files
• Compiler that parses (small subset) of Java bytecode and converts it into MSIL
• Small subset of JNI support (calling native methods & calling Java from native code)

What is needed

• Exception object model mapping needs to be worked out
• Bytecode parser needs much improvement
• Classpath native code needs to be written
• Classpath VM interface needs to be investigated and adapted where necessary
• ClassLoader support
• Flesh out JNI support
• Testing, testing and more testing
• Documentation
