Some background for those who don't know:
Recently a major security flaw in the JRE was discovered which would allow rogue websites to execute code on Windows, Linux, and Macintosh computers without any form of user consent. It has since been widely adopted as a means of attack, and Oracle themselves recommended disabling Java until a patch could be released. Though there is now a patch, the JRE has chronic security problems and unless otherwise needed for web apps such as GoToMeeting, many security experts recommend disabling it from the browser (this would not affect Java development otherwise.)
