This sounds vaguely familiar..
If I understand correctly, the problem is that kaffe uses the thread
inherited from initialization as the first Java thread. Instead, it
should really create a new system thread for the first Java thread,
and then return within the initialization thread.
It might not be too hard to modify kaffe's initialization to do this,
if that in fact would solve your problem.
