Updating a JAR while it's running

I only just saw this video and thought notch's setup was really neat. How do his jars update whenever he saves without him restarting his game?

I know enough Java and have had experience with eclipse but I've never seen this done before and it would really speed my development.

Notch actually answered your question in the video. At 35 seconds he says, "because it's running in debug mode, I can update it while it's running."

In eclipse, debug mode looks like a green bug. It is located (in the default Java perspective) to the left of the green "run" button.

Go into debug mode (looks like a spider or whatever) and it will update your application automatically when you save.
