Todd Baert updated ARTEMIS-1549:
--------------------------------
    Description: 
I have setup a cluster of 2 brokers, using a simple static cluster 
configuration (see below). Sending a CORE message to broker1, and consuming 
that message from broker2 works as expected. Attempting the same over AMQP 
(using the AMQP .Net Lite client) results in an NPE in broker2:

To be clear, the NPE exists on the broker to which the receiver is attached, 
every time a message is SENT by the producer (which is attached to the other 
broker).

Attempting to send/receive the AMQP messages on the same cluster member works 
as expected.

Here is some client code that demonstrates the issue:

{code:java}
using System;
using System.Collections.Generic;
using System.Threading;
using System.Transactions;
using Amqp;
using Amqp.Framing;
using Amqp.Sasl;
using Amqp.Types;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            string url1 = "amqp://localhost:5672";
            string url2 = "amqp://localhost:5673";
            String ADDRESS = "orders";

            Connection connection1 = new Connection(new Address(url1));
            Session session1 = new Session(connection1);
            ReceiverLink receiver = new ReceiverLink(session1, "sub1", 
CreateSharedDurableSubscriberSource(ADDRESS), null);

            Connection connection2 = new Connection(new Address(url2));
            Session session2 = new Session(connection2);
            SenderLink sender = new SenderLink(session2, "sender", ADDRESS);

            receiver.Start(300, (r,  m) => {
                r.Accept(m);
                Console.WriteLine("Got message: " + m.Body);
            });
        
            Message outMessage = new Message("order placed at " + 
DateTime.Now.ToString());
            outMessage.Header = new Header();
            outMessage.Header.Durable = true;                    
            sender.Send(outMessage);

            Thread.CurrentThread.Join();
        }

        private static Source CreateSharedDurableSubscriberSource(String 
address)
        {
            Source source = new Source();
            source.Address = address;

            source.ExpiryPolicy = new Symbol("never");
            
            source.Durable = 2;

            source.Capabilities = new Symbol[]{"topic", "shared", "global"};
            source.DistributionMode = new Symbol("copy");

            return source;
        }
    }
}
{code}

Here is the cluster config from broker1, broker2 is configured accordingly


{code:xml}
      <acceptors>
         <acceptor

      </cluster-connections>
{code}

Message load balancing has no effect on this issue, redistributiuon-delay is 
set to 0 for the address in question.
