drjava- I have heard of people having trouble with JUnit when they start using multiple threads because JTest relies on the Exception mechanism and is only watching the main thread. I'm not sure if that applies in your case because it doesn't look like you're making assertions within a separate thread, but I thought I'd pass along the information in case it is helpful.
