I had a little problem with:

static inline void 
vmExcept_setJNIFrame(VmExceptHandler* eh, const void* start, const void*
end)
{
	assert(eh);
	assert(start != 0);
	assert(start < end);

	eh->meth = VMEXCEPTHANDLER_KAFFEJNI_HANDLER;
	eh->frame.jni.start = start;
	eh->frame.jni.end = end;
}

in exception.h.  The "assert(start < end);" needs to be changed to
"assert(start <= end);" otherwise it will fail if there are no
instructions between the start_label and end_label.  Which seems to happen
with Kaffe_ExceptionOccurred() and if NEED_JNIREFS isn't defined...
