Thor A. Lange commented on HV-425:
----------------------------------

I had a similar problem using Hibernate 3.4.0.GA as JPA 1 provider with WebLogic 10.3.4. The system classpath containing the Oracle patch to enable JPA 2.0 in WebLogic.

In this case it was not enough to add the prefer-application-packages since loading JPA 1 from the application causes problems with the JPA 2 classes in the system classpath. I have ended up using a custom TraversableResolver based on how the DefaultTraversableResolver reacts when no JPA 2 classes is found(see http://docs.jboss.org/hibernate/validator/4.2/reference/en-US/html/validator-bootstrapping.html#d0e2486 for information of how to enable your own TraversableResolver). This way it is possible to avoid activation of the resolver intended for JPA 2.0.
