ConstraintViolationException not logged, only javax.resource.ResourceException: IJ000459: Transaction not active:

We are developing a web application using

• JPA (Hibernate 4.2.11.Final)
• Hibernate Validator (JSR-303)
• JTA
• Two storage units with two different data sources
• Deployed in JAPSS EAP 6.2

Our EntityManagers are configured in a Spring config file with the following related properties:

<prop key="hibernate.transaction.jta.platform">
  org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform
</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
<!-- validate | update | create | create-drop -->
<prop key="hibernate.hbm2ddl.auto">validate</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">false</prop>
<prop key="javax.persistence.transactionType">JTA</prop>
<prop key="javax.persistence.validation.mode">AUTO</prop>

      

        
        
        
      

    

Also declares a transaction manager in Spring

  <tx:jta-transaction-manager />

      

        
        
        
      

    

The problem is that on certain service calls (only a few) when ConstaintViolationException is called, it is somehow replaced with an exception chain logged like this:

I was able to identify the original ConstraintViolationException debugging application, but I don't see it in the log. Even I tried to debug and move the second exception and it doesn't contain the original ConstraintViolationException as the reason, obviously different.

Maybe TwoPhaseCoordinator.beforeCompletion is throwing a second exception after ConstaintViolationException? How can I log this first exception to find out which restrictions were violated?
