Hi please oblige and review the webrev below which addresses the issue
problem: https://bugs.openjdk.java.net/browse/JDK-6458027 webrev: http://cr.openjdk.java.net/~msheppar/6458027/webrev/ the core of the issue is that a windows platform may be IPv6 enabled, but an individual adapter/interface may not be configured with for IPv6. This causes a problem with the MulticastSocket.setNetworkInterface() and MulticastSocket.getNetworkInterface() methods. The solution focuses on adding and additional check on the individual interface for IPV6 enabling. The fallback position when an adapter is not configured for IPV6, is to handled it as IPV4, only. It should be noted that setting an Interface which does not have a valid IP address bound to it will result in a SocketException. As such, i the onus in on the application to supply a validly configured NetworkInterface object to the MulticastSocket.setNetworkInterface(). With this in mind, the set of Interfaces constructed for the associated test is based on the interface being up, multicast, and valid IP address configured. regards Mark
