Continuous stack trace loop after attempting to invoke bpel script that has errors

I was debugging my sample BPEL script and got it to the point where the script compiled OK but had errors when I tried to execute it. Afterwards, I saw a continuous stream of messages (approx one per second ) of the following error. Once this starts happening you're pretty well hosed unless you stop the server, delete <installdir>/server/default/data/h2, and restart.
One time I had to force the server to stop via process kill because it was no longer registering <ctrl-c> from the keyboard.
