Is the creation of Java class files deterministic?
...s not the same, because you have different binaries on each platform (e.g. Win7, Linux, Solaris, Mac). For a vendor, it does not make sense to have different implementations, but any platform specific issue can influence the result (e.g. flie ordering in a directory (think on your lib directory), en...

to trade the former for the latter.
i.e. throwing more hardware or machines at the problem is cheaper than hiring more developers and using a faster, but harder to maintain language. After all, few people write web applications in C.
