Oops, I did not answer you second question.
I'm not an x86 ASM specialist (actually I stopped using ASM on Z80 and 68000) and I cannot answer your question.
That's why I did not made a x64 version of JNative.
If you are skilled in this area (or any other), you're welcome on the JNative team.
The callbacks are working but we may have side effects that we are not aware of.
