Messages are unexpectedly landing on the DLQ as a result of the maximum redelivery attempts being exceeded.

There are behavior differences between a transacted send and a non-transacted send:

• When performing a transacted send, all messages are processed correctly regardless of the set prefetch
• When performing a non-transacted send, messages are unexpectedly redelivered resulting in messages landing on the DLQ

• If the prefetch value is set to zero on the connection (non-transacted), every messages get consumed correctly

• When using the AMQ7 Core JMS client, no messages are sent to the DLQ
