How to reconcile these two seemingly contradictory things? 1. Messages must not be re-routed to a second alternate exchange
http://qpid.2158936.n2.nabble.com/Alternate-Exchange-of-Alternate-Exchange-td7000176.html The AMQP 0-10 specification has a rule ('double-failure' on p216), that states: A message which is being routed to a alternate exchange, MUST NOT be re-routed to a secondary alternate exchange if it fails to route in the primary alternate exchange. After such a failure, the message MUST be dropped. This prevents looping. 2. Orphaned/rejected messages no longer dropped if the exchange they are routed to first has an alternate exchange. https://bugzilla.redhat.com/show_bug.cgi?id=679212 - Josh
