Evaluation:

This bug is probably likely caused by a race condition in the session class. However, we were never able to reproduce this problem ourselves, so the fix might be incorrect.

If you still see this problem with a JDK that has this fix (JDK 5.0u3 and JDK6-b39 or later), please file a new bug.
