QPID-6994: [Java Broker] Run connection delete tasks before disassociating the
virtualhost
> [Java Broker] AMQP connection close might fail to delete temporary queue
> after close of VirtualHost
> ---------------------------------------------------------------------------------------------------
>
> Key: QPID-6994
> URL: https://issues.apache.org/jira/browse/QPID-6994
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.0, qpid-java-6.1
> Reporter: Alex Rudyy
>
> With current implementation of AMQPConnection close we invoke
> VirtualHost#deregisterConnection first before we invoke
> AbstractAMQPConnection#performDeleteTasks. As result, Connection configured
> object associated with VirtualHost is unregistered before connection deletion
> task is executed. If VH is closing at the same time when connection is
> closed, it might happen that after call VirtualHost#deregisterConnection the
> VH can close immediately and the following call to
> AbstractAMQPConnection#performDeleteTasks would fail because queue deletion
> task cannon be performed on already closed virtual host.
> The problem can manifest either a) during Broker shutdown, b) during a
> virtual host node state change (e.g. an operator stopping the virtual host
> node from the console). Stopping the virtual host itself, or a change in
> mastership during a HA election cannot cause this problem.
> The exception like the one below is reported in this case:
> {noformat}
