[hibernate-dev] Wrapping of optimistic exceptions

[Steve Ebersole]

Non-inline code such as this (this process occurs as part of transaction 
handling) is difficult to always wrap.  In general this requires 
delegation to handle properly 
(org.hibernate.proxy.EntityNotFoundDelegate e.g.)

Another idea (that requires a whole separate thread) would be to 
consolidate native Hibernate and JPA codebases as we move into 5.0. 
That would include exception hierarchies as much as possible.
