Without delving into much detail it boils down to patching org.hibernate.ejb.Ejb3Configuration to avoid NPE. Download the class from its source code repository at http://fisheye.jboss.com/browse/Hibernate/entitymanager/trunk/src/java/org/hibernate/ejb/Ejb3Configuration.java and patch it with the following changes:
