Loki666 released to tests in our Beta Testing forum first version of KVM. What is KVM you can ask Here is author's explanation:

kvm is a Java Virtual Machine for embed system like the gp32
it allow you to execute .class files like with a java.exe with only System.out as output (no gfx no sound)
i sould support threadings, events and timers but i have to check my code (its a very first release)

!!! now you can program the gp32 with java !!!

And here is more about release itself:

ok iv ported i very first version of kvm for the gp32
the output is still very experimental... (it display one character then push 'start'... second charcter push 'start'... etc)
put the .fxe and kvm directory in your gp:\gpmm

the two java are the sample class executed in the test.jar
as you can see, the kvm search for a Two.class with a main method in the test.jar
so you can recompile you class, put them in a test.jar file and test it with the kvm

thanx for debug (test threading and events pleaz)
and thanx to Torluswho did Java4gba and released the source code
