AFAIK, there are some ARM proprietary issues with Jazelle which mean it can't 
be included in the Linux codebase. AFAIK, you need to get a Jazelle license 
from ARM.

I know it isn't "real Java", but has anyone considered/tried TinyVM? This is 
the Java VM used for the Lejos programming environment for Lego Mindstorms. 
This is written for H8S, but most of it is C code and should be portable.
