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

I think this is related to this discussion - http://lists.jboss.org/pipermail/hibernate-dev/2015-July/013027.html
and HHH-9905. The map value is indeed not passed along anymore.

I guess you are referring to JPA specs section 3.6.2 Providing the ValidatorFactory.
There it is quite clear that the map passed should be used to pass the instance
to the JPA provider. I guess as you suggest the question is whether 
a later call to 'entityManager.getEntityManagerFactory().getProperties()' is required
to expose the same properties as the ones passed to the factory creation.
Somehow, I would expect so, but I guess that is not explicitly expressed.

I guess that' the way to go.
