[jboss-user] [EJB 3.0 Users] - ejbTimeout java.lang.NullPointerException

I have an EJBTimer stateless session bean. I kick of the timer via a JMX bean and all works fine. It is when I restart the JBoss server that I am running into an issue. I noticed that when I startup JBoss I receive the following error: | | 07:38:22,445 ERROR [GeneralPurposeDatabasePersistencePlugin] Cannot deserialize | java.lang.ClassNotFoundException:
