[jboss-user] [EJB 3.0] - Should EntityManager be transient?

Hello all! This might be a very stupid question. If so, please enlighten me... ;-) I was wondering: According to the specs, a stateful session bean has to be serializable so that the container can passivate it. Most stateful session beans will centain a @PersistenceContext declaring an EntityManager. Now I noticed that javax.persistence.EntityManager does not extend Serializable and thus makes no guarantee about whether the actual EntityManagerImpl injected by the container will be serializable. Should I declare references to EntityManager in my SSBs as "transient" to be on the safe side? Or will I run into other problems?
