------------------------------------
Hi Stack,
that is strange. the jekins run and local run were both fine. My local run
against the latest master branch on linux VM is also fine..
from the openjdk code(suppose similar with oracle jdk code), we hit below null:
{code}
151 * Returns any IPv4 address of the given network interface, or
152 * null if the interface does not have any IPv4 addresses.
153 */
154 static Inet4Address anyInet4Address(final NetworkInterface interf) {
155 return AccessController.doPrivileged(new
PrivilegedAction<Inet4Address>() {
156 public Inet4Address run() {
157 Enumeration<InetAddress> addrs =
interf.getInetAddresses();
158 while (addrs.hasMoreElements()) {
159 InetAddress addr = addrs.nextElement();
160 if (addr instanceof Inet4Address) {
161 return (Inet4Address)addr;
162 }
163 }
164 return null; // <====here
{code}
and
{code}
752 /**
753 * Joins channel's socket to the given group/interface and
754 * optional source address.
755 */
756 private MembershipKey innerJoin(InetAddress group,
757 NetworkInterface interf,
758 InetAddress source)
...
826 Inet4Address target = Net.anyInet4Address(interf);
827 if (target == null)
828 throw new IOException("Network interface not
configured for IPv4");
{code}
the interf comes from below MulticastPublisher code:
{code}
public void connect(Configuration conf) throws IOException {
NetworkInterface ni =
NetworkInterface.getByInetAddress(Addressing.getIpAddress());
{code}
but I do not change it... Where did you run it? which os?
thanks.

> The multicast implementation is intended to map directly to the native
> multicasting facility. Consequently, the following items should be considered
> when developing an application that receives IP multicast datagrams:
> The creation of the channel should specify the ProtocolFamily that
> corresponds to the address type of the multicast groups that the channel will
> join. There is no guarantee that a channel to a socket in one protocol family
> can join and receive multicast datagrams when the address of the multicast
> group corresponds to another protocol family. For example, it is
> implementation specific if a channel to an IPv6 socket can join an IPv4
> multicast group and receive multicast datagrams sent to the group.
> {quote}
> if not specifying family, the ProtocolFamily of the channel's socket is
> platform (and possibly configuration) dependent and therefore unspecified
> the publisher code:
> {code}
> @Override
> public void connect(Configuration conf) throws IOException {
> ...
> Bootstrap b = new Bootstrap();
> b.group(group)
> .channel(NioDatagramChannel.class)
> .option(ChannelOption.SO_REUSEADDR, true)
> .handler(new ClusterStatusEncoder(isa));
> {code}
> looks should use this netty constructor
> {code}
> public NioDatagramChannel(InternetProtocolFamily ipFamily) {
> this(newSocket(DEFAULT_SELECTOR_PROVIDER, ipFamily));
> }
> {code}
