hi, glad to see i'm not the only one with a similar problem. could you let me know when you find a solution ? I will post it here too if I should find it.
about the problem, a similar problem also surfaced when moving from RC3 to RC4, but this time it's in the server thread. It seems that a SerializationException is thrown when the server tries to passivate a stateful session bean. Again this worked fine with RC3. This is the exception: | 03:56:17,872 ERROR [SimpleStatefulCache] problem passivation thread | javax.ejb.EJBException: Could not passivate; failed to save state | at
