fritzFS, as i can see they've taken the Sun's VM code reviewed it, and then wrote their own. There are some places that look similiar to Sun.

drbolsen, to make it work we need the java reversers. Not those who can just decompile jar using jad, but people who knows/reversed the core of Java virtual machine. I've stuck on understanding how the machine works. I saw where the opcodes are executed but i couldn't uderstant how it all works together. How the variables are presented? What are the virtual registers that RIM JVM uses? How it manages the classes and methods? There is multitasking under java. It's not a single process runnig on one JVM. There are multiple processes, there is interprocess communication within JVM processes.
