[Max Rydahl Andersen (JIRA)]

Max Rydahl Andersen commented on EJB-329:
-----------------------------------------

being able to print out which of possible many available persistence units on the classpath that is relevant for the current entitymanager. 

This is primarily to debug what the autodiscovery actually discovered and if you are running multiple entitymanagers logs are not enough if I can't link a specific instance to which of the many autodiscovered and/or manually/explicit configured EntityManagers i'm currently holding on to.

> Max asked for PU name retrieval in EM and EMF. To inject them in PersistenceException and logs, is problematic since not all Hibernate exceptions/logs are catched and rethrown by EM and EMF so it would not be complete.
> Providing programmatic access to the PU name is doable but for what use case?
