optimizations done by javac and jvm

[ranjith kumar]

hi
1) where can I find list of optimizations done by javac(java compiler)
and jvm(java virtual machine)
            Any links please.
2) Any class file compiled by javac can be run by kvm(virtual machine
for J2ME technology)??

What my observation is that same .class file run by jvm on x86 is
faster than the run by kvm on x86(with same memory....etc).
What my goal is to move the optimizations done by jvm to javac, so
that optimized .class file is produced and will be run quickly by kvm.

thanks.
