JDK1.1.8 should work well. My application makes heavy use of sockets (see above), and socket's work well in multi-threaded applications if they are written correctly. > 2) Next problem I encountered was that Java 1.1.8 was giving me the > libc.so.3 file not found.

The 'thread' that is hanging the program is probably trying to do console input. You can't do console I/O in FreeBSD's thread and expect other threads to run. > So, I install the Kaffe 1.0.5 port, and it works. I'm *very* *very* *very* suprised that Kaffe would work, since Kaffe doesn't use kernel threads either. My guess is that somehow the internals are slightly different, or how you're doing inter-thread communications (in essence, how you make threads go and stop) is slightly different from what the Sun JVM expects.
