Dump a stack trace of the JVM and see where it is locked up in the different threads. If you are able to run a 1.5 VM this would be much easier as you could use jps and jstack to dump all of this externally for your running tomcat process. Anyways, get a stack trace for all of your threads, and you can get a better idea of what is going on.
