      Description

      TypedQuery<Tuple> query = em.createQuery("SELECT u.firstname from User u", Tuple.class);

List<Tuple> result = query.getResultList();
List<TupleElement<?>> elements = result.get(0).getElements();

      This breaks at result.get(0) with java.lang.ClassCastException: java.lang.String cannot be cast to javax.persistence.Tuple.
