Subject [jira] [Updated] (AMQ-3488) Temporary queue advisory messages over VM transport prevents connection closure
Date Wed, 07 Sep 2011 22:29:09 GMT

     [ https://issues.apache.org/jira/browse/AMQ-3488?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dan Retzlaff updated AMQ-3488:
------------------------------

    Attachment: TempQueueDeleteOnCloseTest.java

The attached test case demonstrates this bug by having a consumer active on the source connection,
which causes a "Consumer is consuming from the temporary destination" exception when a separate
connection is created and closed.

> ActiveMQTempDestinations hold onto the source connection that created them. When the
source connection is closed, its temporary destinations are deleted. Unfortunately, DestinationInfo
commands convey the destination object with its source connection to all other connections
on the same VMTransportServer. Hence when these other connections are closed, they attempt
to delete the source connection's temporary destination.
> Note that enabling marshaling on the VM transport works around this bug because destination
serialization and deserialization does not maintain the source connection reference.
> This bug was not present in 5.4.2.
