Strange Error under JDK 1.6.0, Glassfish v2, JSF and Linux 64 and a simple solution

I tested the RunAndBikeDB Java EE 5 demo application under Suse-Linux and encountered strange problem. The application was successfully deployed, however after some clicks the following problem appeared in the logs:

The solution was simple: I just upgraded to JDK 1.6u3amd64 and the problem was gone... Interesting enough, there were no references on the web regarding this exception.
