This is a problem with World of Minecraft working on Java 7.
You make it sounds so harsh , they get alot of the same mails saying the clients don't work , another one won't help them find a solution.
I have Java 7 aswell and it works perfectly for me.
It has done this for me on Java 6 and Java 7
Here's this. If you have Java Version 7 Update 4, then you won't be able to play Minecraft at all. You could try re-installing World of Minecraft Client. Here's this, if you type something that does not show letters (For example, Chinese letters,) then it'll crash for sure. So, keep the letters English like.
i dont use chinese letters at all, it crashes just randomly while im moving, i have a feeling its all java, but idk
Well, try updating Java.
Updating Java doesn't work. I've tried it numerous times.
i find that when im using a lot of the hacks quickly, especially super jump, i get the error. i think it has something to do either with it cant cope with lots of hacked movement, or, minecraft.jar doesnt allow the kind of movement World of Minecraft.jar is trying to do
Haydn, it's great that you want to help out and answer questions and give your input, however try to look at the date that posts were made. Answering topics that are 10 months old like this doesn't really do any good.
Nor do they look that far back either. Except for Haydn127.
Yes it sure help to try and do a search on the matter; Try looking "message displayed on a red screen" then do a simple math test to get nothing. "Comparison method violates its general contract" show nothing too. Next, look for "java.lang.IllegalArgumentException" a lot of write up there.
Don't be afraid to do a google search on the subject too. Maybe another player somewhere have already found a solution to yours.
When you have found something going back many months or years then just read it. Don't respond to it as it not only an old post but the platers maybe no longer around to see it anymore.

It seems as if allot of us are getting this error at the moment, it's really weird. It's doing it to me on ALL servers using the client including World of Minecraft: Realms. I get a maximum of around 1-5 minutes of playing time and suddenly this error will appear out of the midst of nowhere. It's kind of annoying really and it's making the World of Minecraft game client practically unplayable.
