A free virtual machine to run Java(tm) code This is Kaffe, a virtual machine designed to execute Java bytecode. This machine can be configured in two modes. In one mode it operates as a pure bytecode interpreter (not unlike Javasoft's machine)\; in the second mode if performs \\just-in-time\\ code conversion from the abstract code to the host machine's native code. This will ultimately allow execution of Java code at the same speed as standard compiled code but while maintaining the advantages and flexibility of code independence.
