Oops, Forgot to say that after the hang If I send SIGTERM (Ctrl + C), I get just this...
12:12:05,263 INFO [Server] Shutting down all services
12:12:05,266 INFO [Default] Shutting down
12:12:05,268 INFO [ServiceController] Stopping 50 services
12:12:05,348 INFO [HypersonicDatabase] Stopping
Since the loadClassLocally() in the stack trace is also in
Hypersonic, I'm guessing that something in Hypersonic
triggers this problem
