Timothy Bish commented on AMQNET-323:
-------------------------------------
I just looked at the Producer code, I didn't realize that it had been
implemented that way. O personally think that incorrect, the point of the
producer methods that don't specify a TTL is that it should respect the set
value in the Producer and not take something from the Message. It kind of
negates the point of having a TTL setting in the Producer and is inconsistent
with the other Message properties like priority and delivery mode which are
always defaulted to the values set in the Producer. If the user wants to
override the set TTL it should be done by calling the appropriate producer send
method.

> 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;
