How do you know that Hotspot does an excellent job of eliminating ABC's? Sun does not tell us the means by which it determines whether ABC's can be eliminated, nor do they provide a mechanism telling us where ABC's have successfully been eliminated (which would allow us to do some reverse engineering and figure out in what scenarios ABC's can be eliminated)... this leads to a question:

Can code be written in a way which would make the compiler better able to eliminate ABC's? I'm not quite sure what this would entail, but I'm curious as to whether or not it can be done.
