Description

ActiveMQ v5.9.1
Apache.NMS v1.6.0.3083

The InitialRedeliveryDelay doesn't seem to work.
I added a try...catch block to display the time and then re-throw so I could see what was going on.

I'm looking to wait 5 seconds initially and then 5 seconds in between each attempt.
You can see the first exception is immediately followed by the second and then 5 seconds in between.

Here is my code and values. It doesn't matter whether UseExponentialBackOff is on or off.

var connectionFactory = new ConnectionFactory(_queueInfo.URI);
connectionFactory.RedeliveryPolicy.MaximumRedeliveries = _queueInfo.RetryCount; // 6
connectionFactory.RedeliveryPolicy.RedeliveryDelay(_queueInfo.RedeliveryDelay); // 5000
connectionFactory.RedeliveryPolicy.InitialRedeliveryDelay = _queueInfo.RedeliveryDelay; // 5000
connectionFactory.RedeliveryPolicy.BackOffMultiplier = _queueInfo.BackOffMultiplier; // 1
connectionFactory.RedeliveryPolicy.UseExponentialBackOff = true;

// _queueInfo.AcknowledgementMode = IndividualAcknowledge
_connection = QueueConnectionFactory.CreateConnection(connectionFactory, _queueInfo.QueueName, _queueInfo.QueueParameters, _queueInfo.AcknowledgementMode);
