Yeah, I got that from RockyMtnMan's link. I've got a little more faith in the Rover now that I know that it isn't using Java.

The hardware on Mars isn't using Java but all the intelligence on the ground is using Java ;-).

I didn't see any mention of what software was actually running on the rover, just the hardware, so it still could have a VM on the rover. Java runs on all platforms unlike Windows.
