-------------------------------------------------------------
Committed an updated version of the previously attached patch.
On the client side the delivery delay can be provided in the address (e.g.
{noformat}ADDR: queue ; { link: { delay: 10000 } }{noformat} or
{noformat}BURL:direct:////queue?deliveryDelay='10000'{noformat}).
Potentially the client might want to detect whether the broker it is working
with supports delivery delay.
I've held off adding a system test which would be by its definition vulnerable
to timing issues on slower/busy machines. Documentation also still needs to be
added.

> Key: QPID-7255
> URL: https://issues.apache.org/jira/browse/QPID-7255
> Project: Qpid
> Issue Type: New Feature
> Components: Java Broker
> Reporter: Keith Wall
> Attachments: QPID-7255.diff
>
>
> Some enterprise messaging systems provide a delayed delivery feature whereby
> a publisher can provide a delivery time when sending the message, with the
> Broker taking care of not making the message available to consumers until
> that time is reached. The Java Broker should provide the same feature.
> In the Java space, JMS 2.0 has standardised this feature, however there is
> no reason why the feature could not be made available to older JMS 1.1
> clients using a Qpid specific header. Also if the BURL or ADDR address
> could hint to the Producer that delivery delay was required for all messages
> produced by it, this would mean message delay could be turned on from
> configuration alone.
