JPA2 / Hibernate on WL 10.3.5: exception in Bean Validation

Question

Hi all,
I am deploying on Weblogic 10.3.5. Our application uses JPA 2.0 and our provider is Hibernate 4.1.7. So far this has been working for us without a problem.
My problems started when I tried to add Bean Validation (JSR-303) implemented by the Hibernate Validation, as I get a strange stacktrace where Hibernate Validator looks up the classpach for loaded JPA providers, and instead of Hibernate, OpenJPA comes up, a version that is incompatible with JPA 2.
JPA 2 + Hibernate work properly for months now, so there is no doubt as to whether JPA 2 has been enabled properly.
Apparently, this has been recorded as an issue on Hibernate Jira ( [HV-425|https://hibernate.onjira.com/browse/HV-425] ), but with a different persistence provider and an earlier Weblogic version (10.3.3 and 10.3.4).
Is there something I have mis-configured that is preventing Hibernate to be picked up as my persistence provider?
This is my EJB code where I try to validate my top-level entity:
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public void saveResult() throws ResultInvalidException{
     ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
     Validator validator = factory.getValidator();
     Set<ConstraintViolation<FullResultsSet>> violations = validator.validate(result);
     if(!violations.isEmpty()) {
          throw new ResultInvalidException(violations);
     result.setCreatedDate(new Date());
     if(result.getRevisionNumber() != null) {
          result.setRevisionNumber(result.getRevisionNumber() + 1);
     } else{
          result.setRevisionNumber(1L);
     if (result.getFullResultsSetId() == null) {
          getEm().persist(result);
     getEm().flush();
}This is my startWeblogic.cmd (I have added the JSF 2 libraries):
