Same comment as the previous one. The https://docs.jboss.org/author/display/AS71/JPA+Reference+Guide#JPAReferenceGuide says that users are expected to set org.jboss.as.jpa.hibernate4.HibernatePersistenceProviderAdaptor as one of the possible values for jboss.as.jpa.adapterClass persistence provider property. Will this no longer be supported and would it impact existing applications?
