"No session currently bound to execution context" using the legacy Hibernate interface in JBoss EAP

Issue

• Using the legacy/native Hibernate interface (SessionFactory/Session) instead of the JPA interface (EntityManagerFactory/EntityManager)
• hibernate.current_session_context_class is set to org.hibernate.context.internal.ManagedSessionContext

• Encountering an exception while obtaining a Session reference
