[Yong Hao Gao (JIRA)]

    [ https://jira.jboss.org/browse/JBMESSAGING-1831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12565443#comment-12565443 ] 

Yong Hao Gao commented on JBMESSAGING-1831:
-------------------------------------------

First idea:

Mark a connection consumer session as a special session (let's call it CCSession), it has an extra counter and a 'markClose' flag. We know this session is exclusively used by CC and only has one consumer.

when a close is called on a CCSession, we mark it and check the counter, if > 0 , do nothing

when deliver a message through this session, we add the counter by 1,
when a message is acked/cancelled through this session, we reduce it by 1. if the CCSession is marked closed, check its counter and close if the counter is zero.
