This is not true, actually. JDK1.1 1997 had JIT. MS had basically exposed the Variant and COM, the windows handles and part of WinAPI. Overriding paint(Graphic) on a native AWT component (say java.awt.Button) did nothing either and so on.
>>Instead of improving the JVM, Sun decided to make money by suing MS. No wonder that bloated piece of slow crap that looks like crap is dying a slow death and stopped being relevant.
JDK1.3 with hotspot compiler (May, 2000) had the fastest JIT by far.
