Stuart Douglas commented on WFLY-2387:
--------------------------------------
Yes, we are now using the contextId API (as of this morning), so the TCCL is no longer required.
The real issue is that you have a bean manager, but you have a phase 1 pre-bootstrap bean manager. It does not have any beans registered, because it need hiberanate to startup first.
The reason for this is because some beans need to inject persistence units, and so to make this work we need hibernate available.
E.g. think about the pathalogical case of an entity listener injecting an EntityManager via CDI. We are required by spec to support this, but it can't happen until hibernate has started, therefore you cannot create the listener instance until after hibernate has started to give weld a chance to start properly.
