> Key: AMQ-4277

> Reporter: Helen Huang
> Assignee: Claus Ibsen
> Fix For: 5.10.0

> Using 5.7 REST API I can GET a message from a topic but if a new message is
> POSTed to that same topic before the GET has been reissued (less than 20ms
> behind the POST and using the same session as the previous GET) the GET will
> timeout with a 204 and does not retrieve the message. This may be as designed
> for topics (queues are not an option) but I am just looking for confirmation.
> I assumed the first GET would have provided a topic subscription and the
> broker would hold a topic message for which there is a subscriber for longer
> than 20ms? This is not a stress test and is recreated with a simple producer
> and a separate consumer usually within the first couple of message exchanges.
> It has been noticed that when the topic message is POSTed without an
> outstanding GET to receive it, the following exception is logged:
> 2013-01-22 01:09:37,484 | DEBUG | Async client internal exception occurred
> with no exception listener registered: java.lang.IllegalStateException:
