@Test
public void testGetForUpdate_releasesBackupLock() {
    Config config = getConfig();
    TestHazelcastInstanceFactory factory = createHazelcastInstanceFactory(2);
    HazelcastInstance instance1 = factory.newHazelcastInstance(config);

    instance1.executeTransaction(new TransactionalTask<Object>() {

        @Override
        public Object execute(TransactionalTaskContext context) throws TransactionException {
            TransactionalMap<Object, Object> map = context.getMap(randomString());
            map.getForUpdate(keyOwnedByInstance2);

        }
    });
    NodeEngine nodeEngine = getNodeEngineImpl(instance1);
    Data keyData = nodeEngine.toData(keyOwnedByInstance2);
    LockSupportService lockService = nodeEngine.getService(LockSupportService.SERVICE_NAME);
    for (LockResource lockResource : lockService.getAllLocks()) {
        if (keyData.equals(lockResource.getKey())) {
            assertEquals(0, lockResource.getLockCount());
