Do not transform IPv4 multicast address to IPv6 anycast address on
dual stack machines
--------------------------------------------------------------------------------------
Key: WFLY-4685
URL: https://issues.jboss.org/browse/WFLY-4685
Project: WildFly
Issue Type: Bug

Affects Versions: 10.0.0.Alpha1
Reporter: Miroslav Novak
Assignee: Bela Ban
If EAP 7.0.0.DR2 is started with -Djava.net.preferIPv4Stack=false (and
java.net.preferIPv6Addresses=false) then JGroups convert IPv4 multicast address
(jboss.default.multicast.address=230.0.0.4) to IPv6 anycast address on dualstack
machines.
This is done in class org.jgroups.conf.PropertyConverters (line 291-295):
{code}
...
if(retval instanceof Inet4Address && retval.isMulticastAddress()
&& Util.getIpStackType() == StackType.IPv6) {
String tmp=prefix + propertyValue;
retval=InetAddress.getByName(tmp);
return retval;
}
...
{code}
This behaviour is overriding user preference to use IPv4 multicast instead of IPv6
anycast. Can this conversion be removed?
