A related bug (I haven't tried this, but I'm pretty sure it would fail):

Query query1 = ((Session)entityManager).createSQLQuery(queryString);
query.setLong(0, page.getId());

NativeQueryImplementor query2 = entityManager.createNativeQuery(queryString);
query.setLong(1, page.getId());

// this line would fail, because both queries use the same ParameterMetadataImpl, but createNativeQuery called setZeroBasedParametersIndex.
return query1.list();
