Edit Question
Title
Body
I have heard that Java must use a JIT to be fast. This makes perfect sense when comparing to interpretation, but why can't someone make an ahead-of-time compiler that generates fast Java code? I know about gcj , but I don't think its output is typically faster than Hotspot for example. Are there things about the language that make this difficult? I think it comes down to just these things: Reflection Classloading What am I missing? If I avoid these features, would it be possible to compile Java code once to native machine code and be done?
