jre6 versus jre7 -- jre7 won't let me log in

[velusip]

Launcher Version: Any, same problem for months up to 3.1.2

Operating System: Linux 3.4.7-1-ARCH #1 SMP PREEMPT Sun Jul 29 22:02:56 CEST 2012 x86_64 GNU/Linux

Java Version: Oracle jre-7.5-2-x86_64

Antivirus Program: lol

Description of Problem:

I can run technic with Oracle jre6, but when I try Oracle jre7 the "Minecraft username:" and "Password:" fields are unselectable. I can't even tab into them. Clicking will not place focus on either field. However, I can click buttons and dropdown menus.

I also can't run the client directly from a terminal. It keeps "rebooting". More in the error messages section. I'd really like to log the output so I can troubleshoot another much more serious bug (when running jre6) and determine if the Java version has something to do with it.
