Subject [jira] [Commented] (ARTEMIS-1794) Confusion when auto removing a queue
Date Fri, 13 Apr 2018 16:43:00 GMT

    [ https://issues.apache.org/jira/browse/ARTEMIS-1794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16437554#comment-16437554
] 

Justin Bertram commented on ARTEMIS-1794:
-----------------------------------------

In your use-case how are the clients of /topic/foo and /queue/foo related?  Are messages sent
to /topic/foo being consumed from /queue/foo?

>                 Key: ARTEMIS-1794
>                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1794
>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: STOMP
>    Affects Versions: 2.5.0
>            Reporter: Lionel Cons
>            Priority: Major
>
> I'm using the following settings to try to mimic ActiveMQ 5 STOMP destination handling:
> {code}
> <acceptor name="stomp">tcp://0.0.0.0:61613?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=STOMP;useEpoll=true;anycastPrefix=/queue/;multicastPrefix=/topic/</acceptor>
> {code}
> This works as expected in most situations.
> However, when subscribing to a queue (via {{destination:/queue/foo}}) and sending a message
to an eponymous topic ({{destination:/topic/foo}}) Artemis reports a fatal error:
> {code}
> AMQ119209 Can't remove routing type ANYCAST, queues exists for address foo. Please delete
queues before removing this routing type.
> {code}
> I guess this happens when it tries to auto delete things.
> Doing the opposite (subscribing to the queue and sending a message to the topic), I get
the same kind of error:
> {code}
> AMQ119209 Can't remove routing type MULTICAST, queues exists for address foo. Please
delete queues before removing this routing type.
> {code}
