I hope this is what I was supposed to do. I'm going to post this to the mailing list, too.

I think I have seen this before... It was a long time ago (before BASE 2.0 was released) and was caused by a bug in one of the early Java 1.5 version. It was fixed in update 4 or 5 or something. Can you try upgrading to the latest Java 1.5 (update 12)?
