[jira] Commented: (MUSE-195) SimpleNotificationProducer.subscribe() should check for duplicate consumers

    [ https://issues.apache.org/jira/browse/MUSE-195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12473725 ] 

Dan Jemiolo commented on MUSE-195:
----------------------------------

What if the two subscribe requests have different filters? What if one of the filters is a subset of another? Getting the semantics you describe could be an expensive test...

> Currently, a client can receive duplicate notifications if a Subscribe request is sent multiple times for the same consumer.  In SimpleNotificationProducer.subscribe(), a check should be added so that it doesn't create multiple resources for the same consumer.
