[jboss-jira] [JBoss JIRA] (JGRP-2305) Get rid of need for java.net.preferIPv4Stack

[Bela Ban (Jira)]

     [ https://issues.jboss.org/browse/JGRP-2305?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban updated JGRP-2305:
---------------------------
    Description: 
New address picking scheme:
* First we detect which addresses are available: IPv4 and/or IPv6 (dual-stack if both)
* When we encounter an IPv4 address:
** If dual-stack or IPv4 stack: use it
** If IPv6-only stack: use it unless it is a class D (multicast) address: then convert it to an IPv6-mapped address
* When we encounter an IPv6 address:
** If dual-stack or IPv6-only stack: use it
** Else: throw an exception (IPv6 address in an IPv4-only stack)

  was:
New address picking scheme:
* If all addresses in the config file are IPv4: use IPv4 addresses if available, else use IPv6 addresses
* If all addresses are IPv6: use IPv6
* If there is one IPv6 address: use IPv6
* If we have an IPv4 address, but the stack is not dual (but just IPv6) -> use IPv6-mapped addresses
