Timothy Bish commented on AMQNET-323:
-------------------------------------
Ok, take your word for it as I don't have time to really look at it right now,
all I can say is that from a cursory glance yesterday I couldn't really
determine when and whose TTL value gets set where. So when someone ask me
about NMS TTL all I can say is, "your guess is as good as mine."
> NMS Client does not respect TimeToLive with Listener callback

> Key: AMQNET-323
> URL: https://issues.apache.org/jira/browse/AMQNET-323
> Project: ActiveMQ .Net
> Issue Type: Bug
> Components: ActiveMQ, NMS
> Affects Versions: 1.5.0
> Environment: Windows 7
> Reporter: Matthew Good
> Assignee: Timothy Bish
> Fix For: 1.5.1, 1.6.0

> Attachments: TtlUnitTest.txt

> When TimeToLive expires while a listener is in a redeliver loop, the
> redelivery never stops. The following unit tests show this. The first unit
> test uses Receive and it works fine. The second uses a listener and it fails.
> I added these tests to AMQRedeliveryPolicyTests
> {code}
> [Test]
> public void TestNornalRedeliveryPolicyOnRollbackUntilTimeToLive()
> {
> using(Connection connection = (Connection) CreateConnection())
> {
> IRedeliveryPolicy policy = connection.RedeliveryPolicy;
> policy.MaximumRedeliveries = -1;
> policy.InitialRedeliveryDelay = 500;
> policy.UseExponentialBackOff = false;
> connection.Start();
> ISession session =
> connection.CreateSession(AcknowledgementMode.Transactional);
> IDestination destination = session.CreateTemporaryQueue();
> IMessageProducer producer = session.CreateProducer(destination);
> IMessageConsumer consumer = session.CreateConsumer(destination);
