Daemon threads are meant more for background work like Garbage
Collection, the JVM can exit whilst daemon threads are still running.
 I don't know the exact composition of your code but the problem you
may be having is that your main class is exiting thus destroying the
daemon threads along with it.  I'd try marking the two threads as
non-daemon.
