Thanks. I played a bit with it by implementing the necessary support
into jamvm (not that hard at all and it looks like this new setup makes
most operations slightly more efficient). You forgot to remove a couple
of unused instance methods which assume some specific VM-specific Thread
representation (int). I cleaned this up and also made the class
uninstantiable and package private.

* vm/reference/java/lang/VMClass.java: Make final and package local.
Add private constructor. Removed all instance fields and methods.
Cheers,
Mark
