Yikes! We're only supposed to require Java 6. And in the past I've removed bots from the rumble for requiring Java 7 and put a note on the participants page for those bots. But with that many, I wonder if it's time for us to just say to use Java 7?
At this point, I'd note that Java 6 is no longer being maintained for security fixes, and has outstanding exploits against it so... better be upgrading to Java 7 for other reasons.
