How to use SetBytesProperty and GetBytesProperty in WebSphere MQ?

I have a problem with SetBytesProperty / GetBytesProperty methods pair on MQMessage class (I'm using WebSphere MQ Client 7.0.1.6). I can successfully send sbyte array in property to queue but once I try to get it back in read message I always get null.

Here is the simplest code I use to reproduce the issue.

[TestFixture]
public class MQQueueTests {

    public const string MessageContent = "<test>This is test message</test>";

    [Test]
    public void PutAndGetMessage() {
        Environment.SetEnvironmentVariable("MQCCSID", "43开发者_运维百科7");
        var properties = new Hashtable
                             {
                                 {MQC.HOST_NAME_PROPERTY, "TestServer"},
                                 {MQC.CHANNEL_PROPERTY, "Test.Channel"},
                                 {MQC.PORT_PROPERTY, 1415} 
                             };

        using (var manager = new MQQueueManager("Test.Queue.Manager", properties)) {
            using (MQQueue queue = manager.AccessQueue("Test.Queue", 
                MQC.MQOO_OUTPUT | MQC.MQOO_INPUT_AS_Q_DEF)) {

                MQMessage message = new MQMessage();
                message.SetBytesProperty("testBytesValue", 
                   new sbyte[] { 8, 12, 22, 48, 68, 71, 92, 104 });
                message.WriteUTF(MessageContent);
                queue.Put(message);

                MQMessage readMessage = new MQMessage();
                queue.Get(readMessage);

                sbyte[] array = readMessage.GetBytesProperty("testBytesValue");
                Assert.IsNotNull(array);  // <-- FAILS!

                Assert.AreEqual(MessageContent, readMessage.ReadUTF());

                queue.Close();
            }
            manager.Disconnect();
        }
    }
}

Something is passed in message property to queue - I can see something in WebSphere MQ Explorer on the server but it doesn't look like my passed array (it even change over time when new messages are received):

When I turn on tracing (strmqtrc) on MQ Client I can see the same value wrote and read by the client:

This is present in log when putting message to the queue:

So in both sending and receiving I see the same correct byte array. But in .NET code the value of the property is null:

Every other GetXXXProperty and SetXXXProperty method pair works without any problem.

Edit:

I validated that it doesn't work on multiple computers running same version of WebSphere MQ clients and I also validated that it doesn't work with another code. It works if I rewrite the test to Java and use Java API instead!

I also have problems with sending any property in message targeted to MQTopic - I get MQException : MRQC_HEADER_ERROR. Again it works in Java without problem.

I am able to get the value. I can see the returned array has the same values as the ones in the sent message. Here is the C# snippet I used.

                MQMessage message = new MQMessage();
                message.SetBytesProperty("testBytesValue", new sbyte[] { 8, 12, 22, 48, 68, 71, 92, 104 });
                message.WriteUTF(MessageContent);
                queue.Put(message);

                MQMessage readMessage = new MQMessage();
                queue.Get(readMessage);

                sbyte[] array = readMessage.GetBytesProperty("testBytesValue");
                Console.Write(array);
