Scott Marlow commented on WFLY-6149:
------------------------------------

Chris, thank you again for the discussion about this issue and your viewpoint.  I think the best suggestion is to have the Hibernate integration ([under wildfly/jpa|https://github.com/wildfly/wildfly/tree/master/jpa]) allow the system property "hibernate.id.new_generator_mappings" override other settings, which is what you had expected but we do not currently do.

I'm leaving this unassigned for now.  If someone wants to do the work, it will be a useful change.  If not, I'll do it.  Add a comment here if your interested in contributing a patch for this change.  I'll try to provide guidance on making the change.

> It would be great if Wildfly offered better control over the properties used for configuring persistence units.
> For instance the 'hibernate.id.new_generator_mappings' setting has proven hard to control it currently requires one to change persistence.xml to turn it off.
> Hibernate supports specifying the properties in various ways, for example via system properties, but wildfly forces the new mappings to be enabled unless the persistence.xml says to disable them.
> There are some suggestions to how [~smarlow] imagines this to be implemented in the forum thread: https://developer.jboss.org/thread/267613
