That won't fix it, however, as Java =/= JavaScript. Disabling the actual Java plugin will work. Disabling the JavaScript plugin will cause 99.99% of websites to fail and still won't fix the problem.
It seems to me they'd make an exception to their patching rule if the security risk were truly this huge. I'm thinking they're already working on it, and will release a patch as soon as it has tested working.
In my previous experiences with Java and Jscript, disabling the script alone in my browser did not prevent arbitrary code execution using Java.
For my first semester of math at university, we needed to use a plugin for the learning/homework platform (MyMathLab) that used Java but not Jscript, and I was compromised by it through Java despite it being disabled.
If this exploit is only known for Jscript, then fine. Turn off Jscript.
Following that experience, I prefer to err on the side of caution with widespread exploits, especially when those who are responsible for patching it haven't said anything about the exploit or a possible fix.
