[jira] [Commented] (AMQ-5476) Batch transactions of priority messages: javax.jms.JMSException: Unmatched acknowledge: MessageAck {commandId = 14, responseRequired = false, ackType = 2, ...Could not find Message-ID XXX in dispatched-list (start of ack)

    [ https://issues.apache.org/jira/browse/AMQ-5476?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14235559#comment-14235559 ] 

Gary Tully commented on AMQ-5476:
---------------------------------

The reordering client side breaks a range ack. Disabling by default b/c when it is enabled individual ack mode is required which for transactions will negate the typical batch use case.
