Before the code Change:
Though building OpenJDK is little cumbersome process but come on, its a one time process. Just make the build ready once and then screw it as you want both on the Java level and on native level . Even more process and standard documents will come as OpenJDK goes into its maturity stage. You will love to know that Netbeans 5.5+ is giving a high class support for making OpenJDK across all platforms.
So for the real die-hard of Java, I am going to write Part II, III, ... upto N(covering some technicalities of building process) till I am not able to make you happy. Thanks to Igor and Sandeep who have replied my all shots of stupid questions.
