There are 2 versions of 'free' JVMs around (Kaffe and Japhar).
Just looking at Japhar (http://www.japhar.org) it is LGPL'd, which is
Just because it is called the Java virtual machine doesnt mean
just java can compile to it. Soon I will have a 'Tiger' (little toy
language to teach comiler writing ML/Pascalish looking) compiler compiling
to it. There is an Ada compiler for the JVM. Although as a 'ground up'
alternative its not the best.
