Hi
   please oblige and review the following change

to address the issue
https://bugs.openjdk.java.net/browse/JDK-8077377

it is possible that "stray" packets can be received in this MulticastSocket test, and this results in a NPE from the NetworkInterface lookup based on the received address.
Change adds a test that the "from" NetworkInterface is not null.
If I read this correctly then it just ignores the packet when it comes from a non-local interface (or interference from something else on the network).

Should the commented out throwing on RuntimeException be removed while you are there?
