Gary Tully created AMQ-3894:
-------------------------------

             Summary: Add support for Broker based redelivery
                 Key: AMQ-3894
                 URL: https://issues.apache.org/jira/browse/AMQ-3894
             Project: ActiveMQ
          Issue Type: New Feature
          Components: Broker
            Reporter: Gary Tully
            Assignee: Gary Tully


redelivery is handled by the consumer, so client side. messages pending redelivery are seen
as inflight by the broker and not available to other consumers. It is possible to break the
order constraint and receive messages backed up behind a message pending redelivery, but this
is all local to the client consumer.
When redelivery is exhausted, the message is returned to the broker with a poison ack, which
the broker responds by removing the message and doing Dead letter queue processing (DLQ).

This enhancement will allow a replacement of DLQ handling that will handle redelivery. It
is based on the ideas outlined and implemented by a camel route in https://issues.apache.org/jira/browse/AMQ-2710


The idea is a BrokerPlugin will override sendToDeadLetterQueue and resend the message to the
original destination in accordance with a matching RedeliveryPolicy. The resend will use the
broker schedular to implement the delayed send after the message has been acked as poison
by the consumer.
So the message will essentially be enqueued at the tail of the queue and dispatched again
to any available consumer.
If retries are exceeded or there is no matching redelivery policy for a destination, normal
DLQ processing will take place.
This will work in conjunction with consumer/client redelivery exhaustion or using a redelivery
policy in the url query of jms.redeliveryPolicy.maximumRedeliveries=0
