Bela Ban created JGRP-2343: ------------------------------ Summary: Change in IPv4 versus IPv6 picking algorithm Key: JGRP-2343 URL: https://issues.jboss.org/browse/JGRP-2343 Project: JGroups Issue Type: Task Reporter: Bela Ban Assignee: Bela Ban Fix For: 4.1.1 When https://issues.jboss.org/browse/JGRP-2305 was implemented, IPv4 was favored unless {{java.net.preferIPv6Addresses}} was set. However, this makes the following case fail: no {{java.net.preferXXX}} option is set and the configuration contains one or more IPv6 addresses, e.g. {{UDP bind_addr="::1"}}. This will fail, as the new algorithm sets the stack type as IPv4 (it works when {{java.net.preferIPv6Addresses}} is set). Change: * Look at all IP addresses in a configuration * If all addresses are IPv6 and the stack type is IPv4 (and IPv6 is available) -> switch to IPv6 as stack type * If all addresses are IPv4 and the stack type is IPv6 (and IPv4 is available) -> switch to IPv4 stack type -- This message was sent by Atlassian Jira (v7.12.1#712002)
