Default Java 7, Windows 7 and IP

Hi,
some of you (or all of you) may know this, but just in case:

JRE 7.X and Windows 7 have an issue, especially on a wireless connection that causes lots of client lag (your hard disk just thrashes bringing the machine to a halt). The issue is caused by JRE attempting to use the IPv6 protocol stack even if you have an IPv4 connection.

There is supposedly an option to force Java to use the IPv4 stack, but it didn't work for me using Mindcrack. The other option is just to disable the IPv6 protocol if you do not have an IPv6 connection (this works nicely for me while Minecrafting - though I have to revert for work).

Cheith.
