I have no idea, I just remember it from the stream from notch. I also experimented a bit with something similar for python. You can find it here: http://www.kr

I have no idea, I just remember it from the stream from notch. I also experimented a bit with something similar for python. You can find it here: http://www.krause-software.com/hotswap/ http://www.krause-software.com/hotswap/ I think it worked so well for notch because the code he was changing was in a different class than the program's entry point, so the virtual machine had it easy swapping the code. Once again, I don't know the details, it is just my impression from what I saw that time.
