[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-325) Any PersistenceExceptions should state which persistenceunit they are from

[Max Rydahl Andersen (JIRA)]

Max Rydahl Andersen commented on EJB-325:
-----------------------------------------

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.
