[cdi-dev] Needed failing for JPA / EJB

[Mark Struberg]

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.
