    ListJoin<Address, Phone> phones = addressRoot.join(Address_.phones);
    criteria.where(cb.gt(phones.index(), 0));
    List<Address> results = em.createQuery(criteria).getResultList();
    assertNotNull(results);
    // Ensure that the "index(phones) > 0" condition was included on the inner join, meaning only address1
    // (> 1 phone) was returned.
    assertEquals(1, results.size());
    assertEquals(address1.getId(), results.get(0).getId());
