----------------------------------
Summary: Non-blocking redelivery does not calculate exponential
delivery properly
Key: AMQ-6368
URL: https://issues.apache.org/jira/browse/AMQ-6368
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.13.3
Reporter: Szymon Jachim
Non-blocking redelivery does not calculate exponential delivery properly when
retries of delivery are interspersed with (successful) deliveries of other
messages.
This is caused by the fact that last redelivery delay is stored in a field and
is overwritten delivery of other messages. A possible fix is that redelivery
delay can be calculated each time by simply doing multiplications in a loop (as
it is done in broker) or using mathematical exponent function. At the same time
redelivery count can not be a single field but an array with a counter per each
message waiting for client side non-blocking redelivery.
I can provide a patch for this and a unit tests.
