I really hate people randomly suggesting that, there IS a reason that Java 7 is still in developer preview phase and not officially released to end users by Sun. Updating to 1.7 can't and won't fix your random MC mod problems and can cause even more problems.
Word of warning: because of my immature reaction below this line, it may be possible the part below that isn't read objectively and constructively anymore!
Me: Yes, because I try to be helpful, it's random spam... Ow wait... Maybe I had a reason?
You: Nah, im better then everyone else is! (I hate them, see above) Ow wait...
It would be more constructive if you had written something like: "Dear Triblade, thanks for the suggestion but I would advise against it because Java (JRE) 1.7 is still in developer preview phase and not officially released to end users by Sun. So please do not use Java 1.7 until it has been officially released and supported by Mojang/Minecraft and this mod. Using your solution could potentially create more problems then it potentially can solve."
And my reaction to the hypothetical sentence above:
The JRE 1.7 install did help a few people in the past and I had this solution from another post on the forums. So it may not be for everyone, but if it helps people without reported consequences, why not?
