--------------------------------------------
Summary: Duplicate messages generated by JMX replay operation when
AMQP broker-connection mirroring is enabled and when the queue is paging.
Key: ARTEMIS-4983
URL: https://issues.apache.org/jira/browse/ARTEMIS-4983
Project: ActiveMQ Artemis
Issue Type: Bug
Components: AMQP, JMX, management
Affects Versions: 2.36.0
Reporter: Jean-Pascal Briquet
Attachments: ReplayWithBrokerConnectionTest.java
*Context:*
Messages are duplicated by the replay capability that recovers messages from
retention folder.
It happens when the broker is configured with an AMQP broker connection,
mirroring is enabled and the queue is paging.
*Investigation notes:*
It appears that several copy of the message exist in retention folder. The
original message is present as expected but an additional occurence with
mirroring property "x-opt-amq-mr-id" is also found.
The ReplayManager while scanning messages in journals of the retention folder,
processes entries one by one, and recover messages regardless of whether they
are duplicates originating from mirroring.
Disabling the AMQP broker connection (and mirroring) in configuration restore
the normal behaviour of the JMX replay operation.
*Test case:*
The test case "ReplayWithBrokerConnectionTest" is provided, just add it under:
_tests/integration-tests/src/test/java/org/apache/activemq/artemis/tests/integration/retention_
When running the test, "testReplayCorePaging" will fail.
