I keep getting an UnsupportedOperationException error on startup something like 80% of the time. If I'm lucky, I don't get it and the server runs fine from then on. Looks like some startup issue. If I remember, there was some thread saying this was the result of a race condition with DataNucleus, but I can't find that thread anymore.
Could someone help please? This is getting a bit frustrating. Thanks!
