I brought up this idea with Lars Bak (HotSpot architect at Sun back then) at a conference some years back when Sun introduced the HotSpot VM. The argument back then was that a program mays not execute in the same pattern every time and the optimization made previously may no longer apply.
True, but if you saved the entire state of the JVM memory on disk (an JVM 'hibernation'?) then you could just start from where you left, instruction pointer included.
Just one _teensy_ snag. Open files and sockets. And all state external to the JVM.
