Is it possible that your application is throwing a run time
exception that you are not logging or catching? We have had a problem
with a JVM (not sure which one right now, but I could find out) where
this issue was causing a silent death. The person who debugged this
should be back in town this weekend, and I will ask him about it and
try to let you know.

Not on my machine. 4.4-RELEASE FreeBSD SMP

I have severe problems with the IBM JDK locking or not exiting. I
have only seen the behavior in ant builds right now, but I have not
tried anything else that is heavy duty with it. My few tests with hello
world applications (even multithreaded ones) couldn't replicate the
behavior. I have spent too many hours playing with it to not try to
warn you off.

I would suck it up and use 1.2.2 native on FreeBSD or possible 1.3
native (although I am not brave enough yet). You will be without JIT
unless you install one, but that might cause problems for you as well
(with space and possibly reliability). OpenJIT was pretty easy to
install, IMHO.
Good luck.
