CXF-6795 WS-Discovery add support for discovery on localhost
This addresses the feature request to add loopback support for UDP
transport and hence WS-Discovery.
https://issues.apache.org/jira/browse/CXF-6795
There was some code which was attempting to guess which network interface
to use for multicast purposes. I have left the ability to configure a specific
interface to use, but I removed the code which tried to guess a default
interface since this is best handled by the operating system's routing table.
The algorithm was essentially making an arbitrary choice from the available
network interfaces, except the loopbacks. However, it is still possible and in
many circumstances desirable to run multicast on the loopback adapter. This
requires the MulticastSocket to be configured with the setLoopbackMode(false)
and setReuseAddress(true) options in order to receive packets which were sent
from the local machine.
In some circumstances, this will not be required, but it shouldn't cause a
major issue since the WS-D packets are so small. Perhaps someone can comment on
impact outside of WS-D for other user of UDPTransport's multicast capability?
