Rob Godfrey commented on QPID-6079:
-----------------------------------
So the issue here is the queue is deleted, but there are outstanding acquired
messages which may be later released. The queue had an alt exchange, but as
per the earlier failure, the alt. exchange should be "deletable" once the queue
is deleted. The ultimate answer is probably to better model the zombie state
of a queue which has had deletion requested, but for which there are still
messages whose state is not settled. Once all unsettled messages have been
settled then the queue could be properly deleted, until that time it should
probably retain the reference to the alt exchange (although bindings to the
queue should disappear, it should no longer be seen as a child of the vhost...
etc).

> URL: https://issues.apache.org/jira/browse/QPID-6079
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.31
> Reporter: Keith Wall
> Attachments: QPID-6079-2.patch
>
>
> Running the Python 0-10 AlternateExchangeTests test suite against the Java
> Broker (trunk with "secureOnlyMechanisms" : [ ] applied to the auth
> provider), I see the following tests fail.
> What's more, after the tests have completed, I notice an exchange (alt1) has
> been left behind by the tests but attempts to delete it manually from
> Management fail without error.
> The REST output shows that alt1 is not referenced as alternate exchange from
> another exchange or queue.
> There are no errors logged server side during tests or subsequent attempts to
> remove the exchange.
> I cannot reproduce the issue with 0.28.
