[hibernate-dev] No ValidatorFactory exposed through "javax.persistence.validation.factory" in WF 10 CR1

[Steve Ebersole]

Its really a different discussion Hardy.  The discussion here is
whether EntityManagerFactory().getProperties() should return values that
were not passed in the Map when building the EntityManagerFactory.

Yes the spec says that ValidatorFactory should be passed as part of the
"configuration Map" when building the EMF.  However, WF does not do it that
way.  Hibernate supports passing the ValidatorFactory in as part of the
"configuration Map", but it also supports this proprietary 2-phase approach
developed for WF.

All that said, there are other cases where we explicitly handle certain
settings to be returned from EntityManagerFactory().getProperties().
Things like Connection info defined in the persistence.xml we explicitly
transfer into the Map backing EntityManagerFactory().getProperties().  So
the question is whether a similar thing makes sense for ValidatorFactory.
