Hi,
I've created a demo with a spring boot application that has defined a listener to activemq broker, I can detect that the redeliveryDelay is not working when the transactionManager is available in the DefaultJmsListenerContainerFactory. I can reproduce it with atomikos and bitronix.
I've attached the project, so you can reproduce the problem.
Thxs.

Sorry it took so long to look at this. Your ConnectionFactory is not XA capable so it's not enlisted as a resource when the transaction rollbacks. I can see that the session is invalidated, which explain why the redelivery is discarded.
You may find this SO question to provide more context.
