If you take C++ and remove the explicit handling of memory (including
pointers), then you are pretty close to Java. Those 'features' can't be
implemented on the JVM (at least not in any close-to-usable way).


In the more general case, I'd say that pretty much any language should be
possible to compile, but the interesting question is if it is possible to
generate _effective_ code. The Java language and the JVM is rather closely
coupled.


I am currently working on a diploma thesis (together with Kjetil Valstadsve)
which aims to look into certain aspects of the question of JVM as a suitable
target for compiled Scheme.


There also is another Scheme interpreter/compiler (by Per Bothner) called
Kawa that does a decent job.
