Max Rydahl Andersen commented on HHH-2981:
------------------------------------------

your exception improvements are great but if you could attach a stacktrace then it would be very helpfull since the same excepiton might need different handling depending on the call sequence to add the info that you are looking for.

> Recently Hibernate gave me this error; it was uninformative because:
> - It doesn't say what object has the reference
> - It's not clear what the given class name refers to
> - It doesn't say what field in that object was being processed.
> It was misleading because:
> - The problem was actually caused by passing a non-persistent object as a parameter to a query, not because of references to a non-persistent object
> So, this sent me in the wrong direction.
> Hope this helps ...
