hello,

i wanna catch ConstraintViolationExceptions when persisting an entity, i 
noticed i had no result at first so i tried this :


  | try {
  |     if (e.getId() == 0 ) {em.persist(e);}
  |             else { em.merge(e);}
  |     } catch (Exception exception) {
  |             logger.info("Caught exception from EntityManager.");
  | }
  | 

which gives no result. it seems the exception isn't thrown by the EntityManager 
operations? i do see the exception in the JBoss log as usual though

anybody got an idea ?
