> If a message enters a redelivery cycle of e.g. 10 maximum redelivery attempts, and the
session is closed halfway through it (e.g. after consuming attempt 5), the next time the session
is established and the message is consumed, it will have RedeliveryCount=2 rather than 6.
As a result, the message will end up being materially redelivered 14 times, thus exceeding
the configured maximum.
> With the current set up, where it's the consumer-side AMQ logic who is in charge of tallying
up the redelivery attempts and sending back the Poison ACK, it seems that there is a missing
command when the session is being closed *gracefully* from consumer -> broker informing
of the redelivery counters of messages in redelivery process.
> If the session was being closed suddenly, I suppose to some extent it would be okay to
miscount the redeliveries, since there was no chance to execute a closure process for the
client to update the broker accordingly.
> This is also a case for AMQ to support broker-controlled redeliveries (see AMQ-3597).

> Unit test reproducing the problem is attached.
