DISPATCH-1181: ensure local variable is initialised before it is used
> handling MAU when local address is not yet defined can result in wrong
> treatment
> --------------------------------------------------------------------------------
>
> Key: DISPATCH-1181
> URL: https://issues.apache.org/jira/browse/DISPATCH-1181
> Project: Qpid Dispatch
> Issue Type: Bug
> Reporter: Gordon Sim
> Assignee: Gordon Sim
> Priority: Major
> Fix For: 1.5.0
>
>
> When dynamically configuring routers in a network, it is possible for an MAU
> from one route rto reach another router for an address that the second router
> has not yet had defined. At present this may cause the wrong treatment to be
> applied to that address, which does not then get updated when the address
> *is* defined. If the default distribution is unavailable then the MAU
> handling exits without mapping the destination.
>
> E.g.
>
> start router 1
> define a multicast address on it
> create receiver on that address & router
> start router 2
> wait a bit before creating the same multicast address
> create receiver on this router using the same address
> send to the address on router 2
>
> The address is treated as anycast (the default distribution). Using qdstat -a
> the incorrect (or undesired) distribution can also be seen.
