-----------------------------------
Summary: Stored AMQP messages are lost when Receiver Link is
opened on remote cluster member
Key: ARTEMIS-1568
URL: https://issues.apache.org/jira/browse/ARTEMIS-1568
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.4.0
Environment: Fedora 26, openJDK8, AMQP .Net Lite client
Reporter: Todd Baert
In a 2-broker cluster, if AMQP messages are sent to broker0, and then a
receiver link (consumer) is connected to broker1, the messages are removed from
broker0, and attempted to be forwarded across the cluster bridge, but are lost.
broker1 shows an NPE:

This is similar (but not identical to)
https://issues.apache.org/jira/browse/ARTEMIS-1542 which was fixed a few weeks
back. In ARTEMIS-1542, the receiver links are present on both brokers are the
time the message are sent. They are now load balanced and received properly.
In *this* issue, the receiver link is created after the messages already exist
in broker0. I'm not sure if the desired behavior is for these messages simply
to stay on broker0 and not corss over to broker1, but right now, they are sent
over the cluster bridge and lost forever.
In this case, it looks like the 2nd arg to
ClusterConnectionBridge.beforeForward() is null. I have attached some native
AMQP client code that demonstrates this issue ( AMQP .Net Lite client, c#):
{code:java}
using System;
using System.Collections.Generic;
using System.Threading;
using Amqp.Framing;
using Amqp.Extensions;
using Amqp.Sasl;
using Amqp.Types;
namespace Amqp.Extensions.Examples
{
class Program
{
static void Main(string[] args)
{
// create receiver link on broker0
Connection connection0 = new Connection(new Address(args[0]));
Session session0 = new Session(connection0);
ReceiverLink receiver0 = new ReceiverLink(session0, "test",
"orders");
// send messages to broker0
SenderLink sender = new SenderLink(session0, "sender", "orders");
Message message = new Message("a message!");
for (var i = 0; i < 5; i++)
{
sender.Send(message);
Thread.Sleep(100);
}
// receive 1 of 5, works as expected...
Message m = receiver0.Receive(TimeSpan.FromSeconds(1));
Console.WriteLine(m.Body);
receiver0.Accept(m);
session0.Close();
connection0.Close();
// create receiver link on broker1
Connection connection1 = new Connection(new Address(args[1]));
Session session1 = new Session(connection1);
ReceiverLink receiver1 = new ReceiverLink(session1, "test",
"orders");
// these 4 messages are removed from broker0 (ack'd) but never
delivered. NPE seen in logs on broker1
for (var i = 0; i < 4; i++)
{
m = receiver1.Receive(TimeSpan.FromSeconds(1));
if (m != null)
{
Console.WriteLine(m.Body);
receiver1.Accept(m);
}
}
sender.Close();
session1.Close();
connection1.Close();
}
}
}
{code}
