Some updates, although I am really not working on this.
Fixed the setup by using
@ExtensionManaged
@Produces
@PersistenceUnit
@ConversationScoped
static EntityManagerFactory producerField;
Then now the same exception is thrown both with @Inject and
@PersistenceContext(type = PersistenceContextType.EXTENDED)
Caused by: java.lang.IllegalStateException: Context is already active
