Josh Byster commented on ARTEMIS-4666: -------------------------------------- Thank you for doing this [~tabish]! I think the issue did come up when I was configuring via the API directly in Java, so I'm wondering if I needed to instead call setQueueMatch and did not do that previously. I can't find the example when I had ran into this issue, but if I do I can try it out. > Federated queue consumers do not receive messages on classic clients > -------------------------------------------------------------------- > > Key: ARTEMIS-4666 > URL: https://issues.apache.org/jira/browse/ARTEMIS-4666 > Project: ActiveMQ Artemis > Issue Type: Bug > Components: Federation > Affects Versions: 2.32.0 > Reporter: Josh Byster > Assignee: Timothy A. Bish > Priority: Major > Fix For: 2.34.0 > > Time Spent: 50m > Remaining Estimate: 0h > > Federated queues with A upstream and downstream to B do not seem to work as > expected when the client JMS implementation is ActiveMQ Classic v5.16.2 (used > in my example, but also verified the issue is present with v5.18.3 and > v6.0.1). With Artemis JMS as the client, it seems to work as expected. > When running a producer on A and a consumer on B with the classic > org.apache.activemq.ActiveMQConnectionFactory, the consumer on B does not > consume any messages that the producer sends. When B is restarted, it then > consumes the messages. > This works properly with ActiveMQ Artemis > org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory. I've > created a minimal reproducible example > [here|https://github.com/josh-byster/artemis-classic-consumer-bug/tree/master]. > Running server1 and server2 and then first starting up the Consumer then > running the Producer class, we can see that no messages are logged in console > by the consumer. When you restart the consumer, the messages are consumed. > This is an issue whether you attach a MessageListener or you call receive() > directly. If you switch the ActiveMQConnectionFactory implementation to > Artemis, it works as expected. > I don't think this necessarily warrants a fix if it's an issue specifically > with the classic client, since the solution is just to upgrade clients to > Artemis. However, if it is something that can be patched on the server, that > would be great. I do, however, think it would be good to note this down in > the docs that it's not supported with classic clients, since I spent a while > debugging it. However, most other features do work as expected with the > clients running the classic version, which is much appreciated as it makes > migration significantly easier. > -- This message was sent by Atlassian Jira (v8.20.10#820010)
