@Test
public void testMapKeyList(SessionFactoryScope scope) throws Exception {
    CriteriaExecutor criteriaExecutor = new CriteriaExecutor() {

        @Override
        protected ResultTransformer getResultTransformer() {
            return null;
        }

        @Override
        protected JpaCriteriaQuery getCriteria(Session s) {
            CriteriaBuilder builder = s.getCriteriaBuilder();
            JpaCriteriaQuery criteria = (JpaCriteriaQuery) builder.createQuery();
            Root<Student> root = criteria.from(Student.class);
            final MapJoin<Object, Object, Order> addresses = root.joinMap("addresses", JoinType.INNER);
            criteria.select(addresses.key());
            /*
						s.createCriteria( Student.class, "s" )
								.createAlias( "s.addresses", "a", Criteria.INNER_JOIN )
								.setProjection( Projections.property( "s.addresses" ) );
				 */
            return criteria;
        }
    };
    HqlExecutor hqlExecutor = new HqlExecutor() {

        @Override
        public Query getQuery(Session s) {
            return s.createQuery("select key(s.addresses) from Student s");
        }
    };
    ResultChecker checker = results -> {
        List resultList = (List) results;
        assertEquals(2, resultList.size());
        assertTrue(resultList.contains("home"));
        assertTrue(resultList.contains("work"));
    };
    runTest(hqlExecutor, criteriaExecutor, checker, false, scope);
