Incorrect redelivery behavior and counters
------------------------------------------
Key: AMQ-1038
URL: https://issues.apache.org/activemq/browse/AMQ-1038
Project: ActiveMQ
Issue Type: Bug
Affects Versions: 4.0.1
Environment: Windows XP Pro
java version "1.5.0_06"
Reporter: Steve Bate
Attachments: RedeliveryTest.java
Our understanding is that the RedeliveryPolicy maxRedeliveryCount controls the
maximum number of times a message will be redelivered (assumed to be a global
count and not a per-consumer count). The behavior we are seeing is that
messages are redelivered more times than we specified. The problem may be
related to the way the redelivery counter is being maintained. We see the
redelivery counter incrementing by one for redeliveries to a specific consumer,
but then it resets to a lower number when the message is redelivered to a
different consumer.
I have attached a test case to demonstrate the problem. The first test is a
simple baseline example that passes. The second test shows that messages are
being redelivered too many times for the redelivery policy. The third tests
catches a regression in the delivery count (redelivery count + 1) when sending
a rolled back message to a new consumer.
The test suite uses an embedded broker using the VM protocol so it should be
standalone.
