I'm getting error "java.lang.ClassCastException: org.hibernate.id.enhanced.SequenceStyleGenerator cannot be cast to org.hibernate.id.IdentifierGenerator" when deploying Seam 2.2 application in EAP 6.

Issue

After applying the solution for ClassCastException when deploying a Seam 2.2 application using Hibernate in JBoss EAP 6 the issue persists.

A custom module for Hibernate 3.5 is created in EAP 6 in this case.

The error in the log:
