Re: [cdi-dev] Needed failing for JPA / EJB
Yes, I think it's reasonable to say that you can't in Java EE 6 inject an XPC into
a CDI bean. We should look at changing this, though, especially as we add transactions to
managed beans, it may make sense to offer an extended PC here in the future.
Can you clarify what you mean by an unmanaged EM? As @PersistenceContext always gives you
a managed EM, and I think it be very odd to change this. Also, as managed beans will have
transactions, I really don't think we want to force people to use unmanaged EMs.

Yup this caused a lot confusion because some containers silently
inject an Unmanaged EntityManager if it's not an EJB, others inject a Managed
EntityManager _despite_ it's not an EJB, ...
I'd say we should either define that it should inject an unmanaged EM or define to
throw an Exception in that case.
