The *whole point* of closed-source is that the source isn't available. If Java bytecode is trivially turned back into meaningful source, then closed-source Java ain't closed-source anyway. >> >>> 2) From-source builds may be more complex or resource consuming than >>> could be accommodated on the machine the customer used to launch, e.g. >>> a hand-held device. >> >> I've worked on a Java VM enough to know that won't be a problem. >> > > Why waste your batteries running deep and complex front-end optimizers > that have nothing to do with the target platform? > The compiler's not going to do any deep analysis of code that's versioned out for a different platform. Just lexing, maybe parsing, and that's it. AIUI, the real battery-eating processing is elsewhere, mainly in stuff that's also going to be done by any decent JIT engine. (Not that there wouldn't be at least *some* saved cycles.)
