[jira] Commented: (AMQ-1952) JMSXDeliveryCount is not being incremented correctly

["Hiram Chirino (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/activemq/browse/AMQ-1952?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=45972#action_45972 ] 

Hiram Chirino commented on AMQ-1952:
------------------------------------

I think we may need to extend the wire protocol a bit to gracefully handle this. When the consumer closes, it should let the broker know the last message id that was delivered to the client. That way the broker can mark all the messages between the last one acked and the last one delivered to the client as being redelivered and the rest would not get marked as being redelivered.

But even without the wire protocol change, this case should work today if the prefetch is set to 0.

> There seems to be a problem with respect to the Redelivered and JMSXDeliveryCount
> properties, in that these properties are being incremented even when the message
> has never been re-delivered to the consumer (i.e. on initial message delivery).
> The behavior appears to be happening when there is > 1 messages in the queue,
> the second message and subsequent messages show the redelivered property set to true and
> JMSXDeliverCount property with a number greater than 1, when those messages have not been
> re-delivered before.
