2.3 IPv6 support Regression

[konrad]

Hi folks,

After upgrading HZC to 2.3 (latest) IPv6 is no longer working with TCP
join. We have 2 major problems:

1. Without setting the new interface networkConfig.setPublicAddress(),
the system will pick one by itself. The selected address will be in
the format: ipv6%scope. When calling Member.getInetSocketAddress() we
are getting null. The reason for that is that Address class is trying
to add the scope again in getScopedHost() method and the MemberImpl
will get an UnknownHostException.

2. Ok, So we have set the PublicAddress. Now TCP IP joiner is no
longer works. For some reason nodes are not discovering each other
altought everything looks ok on the logs. Our nodes can come up with
any interface or with specific one. In non of these cases we are able
to work. It is important to mention that this was ok in 2.1 and 2.2.
This is the configuration we are using:

InetAddress bindInet = InetAddress.getByName(bindInterface);

if (bindInet.isAnyLocalAddress()) {
config.setProperty("hazelcast.socket.bind.any", "true");
interfacesConfig.setEnabled(false); // will use
0.0.0.0 / ::1
networkConfig.setPublicAddress(Which.serverAddress()); //
Some public IP
} else {
config.setProperty("hazelcast.socket.bind.any", "false");
interfacesConfig.setEnabled(true);
Collection<String> inters = new LinkedList<String>();
inters.add(bindInterface);
interfacesConfig.setInterfaces(inters);
networkConfig.setPublicAddress(bindInterface);
}

We are using tcpIpConfig.addAddress(); to specify potential members to
join.

Here are the logs:

As you can see each member is trying to connect the other.

Hi,

Thanks for report. I am able to reproduce the issue and working on a fix. 

ps: You should not use  networkConfig.setPublicAddress(), it is just there to support NAT-aware environments. See
