Launcher Disables IPv6


Question

Launcher Version: 253

Operating System: Windows 7 x64

Java Version: java version "1.7.0_17" Java SE Runtime Environment (build 1.7.0_17-b02) Java HotSpot 64-Bit Server VM (build 23.7-b01, mixed mode)

Antivirus Program: None

Description of Problem:

When attempting to connect to an IPv6 server by IPv6 address, Tekkit launched from the Technic launcher fails with the message:

Failed to connect to the server

java.net.SocketException: Protocol family unavailable

I am guessing that this is either related to this upstream bug, about launchers messing with the IP version settings:

https://mojang.atlassian.net/browse/MC-3776

Or to this upstream bug, about Minecraft itself doing the same thing (although this is not supposed to affect 1.5.2):

https://mojang.atlassian.net/browse/MC-19301

The fix (as long as Minecraft 1.5.2 is running) would be to make the Technic launcher not do what the vanilla launcher is described as doing here:

https://mojang.atlassian.net/browse/MC-3776?focusedCommentId=58527&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-58527

Fixing this bug when running Minecraft 1.6+ might require adding a mod that forcibly undoes these changes, as (I have been told) Mojang decided to add them to the client itself in later versions for some reason.

Error Messages:

Failed to connect to the server

java.net.SocketException: Protocol family unavailable
