IQueue accepts null values from HazelcastClient

[tlamerig]

public class IQueueTest {
    private static final String Q = "q";
    private HazelcastInstance instance;
    private HazelcastInstance client;

    @Before
    public void setUp() throws Exception {
        instance = Hazelcast.newHazelcastInstance();
        client = HazelcastClient.newHazelcastClient();
    }

    @After
    public void tearDown() throws Exception {
        client.shutdown();
        instance.shutdown();
    }

    @Test(expected = NullPointerException.class)
    public void addNullShouldThrow() throws Exception {
        IQueue<String> myQueue = client.getQueue(Q);
        myQueue.add(null);
    }

    @Test(expected = NullPointerException.class)
    public void putNullShouldThrow() throws Exception {
        IQueue<String> myQueue = client.getQueue(Q);
        myQueue.put(null);
    }

    @Test(expected = NullPointerException.class)
    public void queueShouldNotBeAbleToContainNull() throws Exception {
        BlockingQueue<String> q = client.getQueue(Q);
        q.add(null);
        q.add("hello");
        assertEquals(2, q.size());
        q.poll();
        String hello = q.poll();
        assertEquals("hello", hello);
    }
}
