Mule JMS Max Redelivery Exceeded Sonic and WMQ - exception

Question

I have a mule flow which reads messages from a sonic topic and publish to a Websphere MQ Topic.
The flow is synchronous and transacted.
I have set maxRedelivery="10" in the inboud endpoint. but it keeps on trying to redeliver.
Here is the exception I get:

Answer 1

This is expected behavior, the above exception is raised when the maximum redelivery count defined in maxRedelivery has been exceeded by your JMS provider. See the answer by David Dossot here: jms Mule max redelivery exceeded
