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

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!
