Summary: [0-8..0-091] Active queue declare no longer to validate an
existing queue's durability (was: [0-8..0-091] Active queue declare no longer
to validate queue durability )

> Key: QPID-6361
> URL: https://issues.apache.org/jira/browse/QPID-6361
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Keith Wall
> Fix For: 0.31
>
>
> Currently on the [0-8..0-91] path in the Java Broker, queue.declare with an
> argument of passive false will close the channel if the queue already exists
> but has different durability. The message is "cannot re-declare queue qqqqq
> with different durability (was: xxxxx requested yyyyy)".
> As the default behaviour of the AMQP JMS Client 0-8..0-91 is to automatically
> declare queues as a side effect of consumer creation, this effectively means
> that the knowledge of a queue's required durability needs to be spread across
> all applications. For installations typical of large institutions, this is
> operationally inconvenient and inflexible.
> The relevant AMQP specifications make no statements regarding the required
> behaviour of an active queue.declare if the queue already exists with a
> different durability.
> This change will remove the validation. In future, if the queue already
> exists, the queue declare will succeed even if durability is different. The
> validations around exclusivity,. auto-delete, and the non-passive flag are
> unaffected by this change.
