[jira] [Commented] (AMQ-6943) ActiveMQ.Advisory.Producer.Queue listener receives RemoveInfo instead of ProducerInfo

["Christopher L. Shannon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMQ-6943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16426921#comment-16426921 ] 

Christopher L. Shannon commented on AMQ-6943:
---------------------------------------------

This is correct behavior and not an issue (the documentation probably just needs updating).  The remove info will contain the producer Id so you can use that to figure out when a producer was removed. 

If you want to know when a destination has no more producers you could figure this out by listening for the producer creation advisories and then tracking all the producers on a destination somehow (map or some other data structure, etc). Then when the RemoveInfo is received you can get the producer Id and remove that producer from your tracking.

> According to the page [http://activemq.apache.org/advisory-message.html] when listening to the advisory ActiveMQ.Advisory.Producer.Queue a ProducerInfo should be sent when a producer starts/stops. The ProducerInfo message is sent with the expected value in the "producerCount" attribute when the producer is created, however on calling producer.close() I receive in my listener a RemoveInfo message.
> My intention is to detect when a queue has 0 producers so I can terminate the consumer so the Queue can be deleted by the gcInactiveDestinations support however the RemoveInfo has no getDestination() member to provide information on what queue the closed producer was attached to.
