--------------------------------------------------------------
We wrote our own persistence provider which extends the HibernatePersistence class and used it in the persistence.xml
Unfortunately on server startup the following exception occurrs:

08:32:08,555 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC00001: Failed to start service jboss.deployment.subunit."green-ear.ear"."green-ejb.jar".INSTALL: org.jboss.msc.service.StartException in service jboss.deployment.subunit."green-ear.ear"."green-ejb.jar".INSTALL: Failed to process phase INSTALL of subdeployment "green-ejb.jar" of deployment "green-ear.ear"

I looked into the source code and found the following entry in the class JPASubSystemAdd:

PersistenceProviderAdapterRegistry.putPersistenceProviderAdaptor(
                        "org.hibernate.ejb.HibernatePersistence", new HibernatePersistenceProviderAdaptor());

So Hibernate is set as the default persistence provider, and I could not find any other location in the code, where a persistence provider ist set. Therefore the method call "PersistenceProviderAdapterRegistry.getPersistenceProviderAdaptor(pu.getPersistenceProviderClassName())" in the method addProviderProperties in the class PersistenceUnitDeploymentProcessor always returns null since no other persistence provider than the default one seems to be registered. Or did I miss something? In JBoss AS 6 this worked as expected.

Thanks!
