Project: TomEE
Issue Type: Bug
Affects Versions: 1.5.0
Environment: Windows 7 x64; jdk1.7.0_09 32 bit;

Priority: Critical
1. Create class EntityManagerProducer:
@SessionScoped
@Stateful
public class EntityManagerProducer implements Serializable {
@PersistenceContext(type=PersistenceContextType.EXTENDED)
private EntityManager em;
@Produces
public EntityManager getEntityManager() {
return em;
}
}
2. Create injection client:
@Named
public class A {
@Inject
private EntityManager em;
public String getDelegateClassName() {
return em.getDelegate().getClass().getCanonicalName();
}
}
3. Create JSF page and try to call getDelegateClassName():
<h:body>
EntityManager is open: #{a.delegateClassName}
</h:body>
4. Deploy (successful) and run the application - observe error message (printed
in browser):
