want to push the mantra that JITing is the be all and end all
of compiler optimization, and doing any kind of compile-time
optimization would be admitting that compile-time is also
important (and somehow making Java more prone to direct
performance comparisons to other languages/platforms?)
Perhaps you're being a little paranoid. I think they don't want
to do optimization in the compiler because this would remove the
incentive/pressure to implement those optimizations in the JVM,
which is bad for all other languages/compilers that target the
JVM. For the JVM-ecosystem it is best if as many optimizations
possible are implemented in the JVM.
If you look at existing benchmarks Java is comparable to many
other languages/platforms with regard to performance.
