java/nio/channels/DatagramChannel/PromiscuousIPv6.java currently has a programmatic check for the OS platform, and throws a Skipped exception for those OS platform which will not run the test.
In line with some recent changes, change the test to use @requires for platform selection

    private static boolean supportedByPlatform() {
        return Platform.isOSX() || Platform.isLinux();
    }

   public static void main(String[] args) throws IOException {

        boolean hasIPV6MulticastAll;

        if (!supportedByPlatform()) {
            throw new SkippedException("This test should not be run on this platform");
        } else {


This can be changed to

@requires (os.family == "linux") || (os.family == "mac")
