[jboss-jira] [JBoss JIRA] Commented: (JBMESSAGING-1723) Queue's delivering count == -1

[Tim Fox (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBMESSAGING-1723?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12518503#action_12518503 ] 

Tim Fox commented on JBMESSAGING-1723:
--------------------------------------

I don't think this is a bug. It's simply because sometimes the message can be acknowledged (which decrements the delivery count) before the call to deliver it returns (which increments the delivery count).

It should never be -1 for any significant period of time, so should cause no problems.

If it is observed to be <1 for any longer period of time I would consider that a bug and this can be re-opened.

> Delivery count of a queue is sometimes -1. See the picture attached.
> Seen on EAP 5 CR3, Sun JDK 6 for Linux.
> Steps to reproduce:
> 1) Start a client sending messages,
> 2) Start a client receiving messages,
> 3) Watch the stats. If you're lucky enough, you'll see it being -1.
