[jira] Resolved: (AMQ-2021) durable subscriber gets stuck while using persistent delivery mode and client acknowledgment with session.recover().

Posted by "Gary Tully (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/activemq/browse/AMQ-2021?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gary Tully resolved AMQ-2021.
-----------------------------

       Resolution: Fixed
    Fix Version/s: 5.3.0

resolved in r729038.
Problem is in dispatch to the DLQ for topics. A property is set in the message before dispatch to the DLQ but this can invalidate the message for delivery to other topic subscribers. The failure can be a little odd as it can result in empty properties at the consumer or marshal errors.
The solution is to copy the message before making modifications.

ps: thanks for the test case :-) I committed a variant of it that catches the various failure scenarios.
