Hello, thanks for the new release, am very excited to be able to use JMS 2.0 with QPID!
While trying to use 0.20 with Azure Service Bus (through AMQP 1.0), I run into the issue of the library complaining "feature not supported", when I set a delivery delay to a MessageProducer. Upon inspecting the source code, QPID seems to recognise the capability flag "DELAYED_DELIVERY" from the connection's properties. Does it mean the broker implementation has to advertise DELAYED_DELIVERY verbatim for it to work? Looking through the AMQP 1.0 specs no mention of DELAYED_DELIVERY was found. On Azure it says it "supports AMQP 1.0 scheduled message", which I believe might be similar, however, it says it uses the "Management Version 1.0 working draft": https://docs.microsoft.com/en-gb/azure/service-bus-messaging/service-bus-amqp-request-response I suspect there probably is a major misunderstanding on my part on how AMQP 1.0 specify features. My current impression is that AMQP itself does not define scheduled or delayed delivery, but it is up to implementations to define it at a level higher than AMQP. Can anyone shed some light? Thanks!
