----------------------------------------
Summary: AMQP Session address query cache can have invalid state
for long lived sessions
Key: ARTEMIS-4801
URL: https://issues.apache.org/jira/browse/ARTEMIS-4801
Project: ActiveMQ Artemis
Issue Type: Bug
Components: AMQP
Affects Versions: 2.34.0
Reporter: Timothy A. Bish
Assignee: Timothy A. Bish
Fix For: 2.35.0
The AMQPSessionCallback retains a map of AddressQueryResult instances for
previous address checks. This map is not updated if the state of broker
addresses changes, neither addresses added, removed or updated states are
reflected in the cache. This leads to issues for long running sessions where a
link attach may fail for a non-existent address and on a later attempt should
succeed if the address was added but can't because the cache will still hold
the non-exists query result. Other scenarios are possible such as an address
removed and re-added with different routing type but the former case is more
serious.
The cache should be removed and if a similar optimization is actually found to
be needed a better mechanism should be chosen to avoid the issues found.
