Steven Radack commented on HHH-1293:
------------------------------------

We're getting the same type of exception on our Linux system.  We were able to get around the error by passing the -server argument to the VM.  We were not able to reproduce the error on our Windows development systems.

> The exception varies with the actual persistent class in use. Most people seem to be using JDK 1.5 and Linux. Some reports say that the exception does not happen from the very start of the application, but it takes "several invocations"/"some time" until it appear, but then it appears very often.
