> When Remote Procedure Call (RPC) communication pattern is used RabbitMQ Camel
> component creates server-named auto-deleted temporary reply queue. Next, the
> queue is bound to the exchange with routing key equal to queue name.
> Likewise, ReplyManager's replyTo field is set with the value of the queue
> name. Reply queue created in this manner is then reused for subsequent RPC
> requests and message property rabbitmq.REPLY_TO is copied from the value
> stored previously by ReplyManager.
> When some network error suddenly appears causing connection failure,
> RabbitMQ's automatic recovery kicks in and tries to recover affected entities
> (assuming the connection was created with automatic recovery enabled, which
> is default.). As temporary quueues are auto-deleted, during recovery process
> a new temporary queue is created which has a new name that differs from the
> original one and here is where the problem begins.
> Creation of the new temporary queue is NOT detected by ReplyManager and
> therefore replyTo property is NOT updated. Also, routing key no longer
> matches queue name. This causes a problem when some implementations of
> RabbitMQ client, like. Spring AMQP, are used server-site. RPC service
> receives our request, processes it, and replies to default exchange with
> routing key equal to rabbitmq.REPLY_TO sent in our request. RPC service
> provider perceives no problem as response is sent successfully but RabbitMQ
> Camel Component keeps awaiting for the response to arrive to the original
> temporary queue which no longer exists due to connection failure and
> recovery. Eventually, Camel throws ExchangeTimedOutException.
> Example:
> # After automatic recovery, a RPC request is sent to example-exchange with
> rabitmq.REPLY_TO=amq.gen-0lLvpnj4ZMlkhxZIcCPVpA
> # After 20 seconds org.apache.camel.ExchangeTimedOutException is thrown:
> {code:java}
> The OUT message was not received within: 2 millis due reply message with
> correlationID: Camel-ID-hostname-1583401848872-0-1690397 not received on
> destination: amq.gen-0lLvpnj4ZMlkhxZIcCPVpA.
> Exchange[ID-hostname-1583401848872-0-1690391]{code}
> # Using RabbitMQ Management WebApp (rabbitmqctl) we check example-exchange's
> bindings and see that routing key amq.gen-0lLvpnj4ZMlkhxZIcCPVpA now
> corresponds to queue amq.gen-zaRCP-p-JbXeSzJmzSp83g
> *Proposed solution* is to add QueueRecoveryListener to notify when temporary
> queue name changes due to recovery. On event, replyTo field will be updated
> with the new temporary queue name and the queue will be rebound to the
> exchange so that routing key matches queue name again. The change will be
> made to org.apache.camel.component.rabbitmq.reply#createListenerContainer.
> Attached patch also contains integration test.
