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

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.
Queue's delivering count == -1
------------------------------
Key: JBMESSAGING-1723
URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1723
Project: JBoss Messaging
Issue Type: Bug
Components: Messaging Core
Affects Versions: 1.4.3.GA
Reporter: Ondrej Žižka
Assignee: Howard Gao
Priority: Minor
Fix For: 1.4.0.SP3.CP11, 1.4.7.GA
Attachments: JMS_delivCount_-1.png
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.
I haven't found anything about this in the docs:
