------------------------------------------
[~toddbaert] Can you try a snapshot from master?
> AMQP messages aren't redistributed across cluster bridge, NPE in
> ServerSessionImpl.send()

> Key: ARTEMIS-1549
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1549
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: AMQP, Broker
> Affects Versions: 2.2.0, 2.3.0, 2.4.0
> Environment: AMQP .NET lite client, .NET Core runtime 2.0, connecting
> with brokers on local machine (fedora 26)
> Reporter: Todd Baert
>
> 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:
> {code:none}
> 08:44:28,061 ERROR [org.apache.activemq.artemis.core.server] AMQ224016:

> 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;
> }
