Had full-on exposure to the Sun .class file format today. I've always been reasonably happy with most of the bytecode itself, but haven't had much reason to look at the whole file format until now. It seems to be quite heavily tied to the guts of Sun's classic VM. I guess I now have a better idea why writing a cleanroom VM is such a major undertaking. The schedule for the bytecode library has slipped slightly since my parents turned up in Cambridge, but maybe I'll get it finished tonight.
Real life: looking around for something a bit more active to do (but preferably not too much running round in circle). I think I might give fencing a try.
