I confirm this problem with the following environment:
-Wildfly 8.1
-Spring 4.0.6
-Hibernate 4.3.5
-Envers
-MS SQL 2012

To receive cause of problem (javax.validation.ConstraintViolationException) I have to temporarily disable envers:
<prop key="hibernate.listeners.envers.autoRegister">false</prop>

Do you think that this is also problem in Envers?
In my opinion when transaction is marked as rollback only, then Envers should do nothing.
