Robbie Gemmell updated ARTEMIS-5519:
------------------------------------
Description: If a broker reports that it supports shared durable
subscriptions the AMQP bridge address receiver could use those types of
subscriptions to avoid a potential corner case where many rapid cycles of
consumer demand being added and removed can lead to a race on processing the
detach frame and allow the previous link to be stolen right before it is
remotely closed. This corner case does not happen in most scenarios due to the
presence of the link credit drain out and the idle link keep alive delay but
depending on those configurations it is still possible. By default this change
prefers using shared subscriptions. (was: If a broker reports that it

By default this patch does not switch to always using shared subscriptions as
that can leave an orphaned durable queue if already using durable address
subscriptions but we can eventually move that direction in a major version
update. )
