Hi,
Could someone please review my fix and CSR for issue JDK-8233307 'MulticastSocket getOption(IP_MULTICAST_IF) returns interface when not set'?
The IP_MULTICAST_IF socket option is specified to have an initial value of null to mean that the interface has not been set. However, if MulticastSocket.getOption(IP_MULTICAST_IF) is called when the interface is not set, it returns a dummy NetworkInterface.
This fix changes the getOption() method to return 'null' as specified instead of a dummy networkInterface.
