Ganesh Murthy resolved DISPATCH-779.
    Resolution: Fixed

> Credit is not issued for multicast address when no receiver is connected
> ------------------------------------------------------------------------
>                 Key: DISPATCH-779
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-779
>             Project: Qpid Dispatch
>          Issue Type: Bug
>    Affects Versions: 0.8.0
>            Reporter: Jakub Scholz
>            Assignee: Ganesh Murthy
>             Fix For: 1.0.0
>         Attachments: dispatch.log, producer.log, qdrouterd.conf, receiver.log
> When I configure a multicast address in the Dispatch router, I expect that my producer
should be able to send the multicasts even when no receiver is connected (i.e. the messages
will be dropped). However, it seems that Dispatch will not issue any credit to the producer
unless there is some receiver already connected and the producer is therefore stuck waiting
for the credit.
> Attached are the logs from both Dispatch as well as producer / receiver. I attached also
the router configuration file. It seems that the same problem appears also after the receiver
disconnects. The producer can still use the remaining credit which was issued before, but
the credit is not refreshed.
> This problem seems to be both with 0.8.0 as well as with the latest master.
