Does Sun's JVM on Windows include a JIT compiler



It's actually even cooler than just a JIT ... Not only does it do JIT compiling, but it will do dynamic inlining and unlining along with a bunch of other optimizations based on runtime analysis. I always love going to the sessions about this part of Java (Hotspot) at JavaOne to hear those guys talk even though they quickly go over my head.
