[hibernate-dev] Feedback on the idea of PersistenceProviderResolver.getPersistenceProviders() caching the same org.hibernate.ejb.HibernatePersistence class instance for multiple application deployments to share ...

Hello, How would Hibernate ORM react to its persistence provider class instance being used with multiple application deployments? Is there any "per application" state in the ORM persistence provider class instance? A few different implementations of javax.persistence.spi.PersistenceProviderResolver.getPersistenceProviders() are not caching the returned PersistenceProvider class instances. [1] raised the issue with the WildFly PersistenceProviderResolver.getPersistenceProviders() not caching the provider class instances for reuse. Same question for OGM, is there any "per application state" in the OGM persistence provider class? Scott [1] http://lists.jboss.org/pipermail/wildfly-dev/2014-September/002984.html is the thread which raised this as a performance issue.
