I agree with Alan here, it is best to check isUp also.
Alan created the following bug for this:
6884837: "test/java/net/MulticastSocket/SetOutgoingIf.java should

I see you have push access, so if you make the appropriate changes
(mentioned above) I can review the webrev and you can use the above bug
number and description to push the changeset.
P.S. I wonder if we have a similar issue with some of the other
