Description
The delivery-count field in the AMQP 1.0 message header tracks prior unsuccessful delivery attempts and so should go 0,1,2. In testing against the 5.11-SNAPSHOT I see the value going from 0 (unset, default) initially, to 2, then 3, etc, following repeated rollbacks. I have tracked this to a defect in the proton-jms contrib artifact and corrected it via PROTON-704, for inclusion in Proton 0.8.
The issue can be seen in the below snippets of protocol trace (at the lines marked <<<<<). When the message is first transfered to the client, the delivery count field is null / not set, giving the default value of 0. Later when the message is sent again after a rollback, the delivery-count header has incremented to 2 rather than 1.
