Not a JDT/Core issue. Moving to web tools for comment.
Looks like a problem in the J2EE EMF models. Perhaps, thread "Worker-21" is the problematic one. Unfortunately, I am not quite familiar with these models. Could some of the other JEE Tools committers take a look?
You seem to have encountered bug 315286 which, unfortunately, was fixed in WTP 3.2.1, while you are using WTP 3.1.2 (guessing from your build identifier). The EMF models are attempting to initialize each other in a non-thread-safe way. We just announced Helios SR1, which contains the fix for your issue. I would highly recommend using that, if at all possible. *** This bug has been marked as a duplicate of bug 315286 ***
Still happens with Version: Helios Service Release 1 Build id: 20100917-0705
