I must admit, I don't feel any urge to keep my code compliant with the 1.1jvm anymore.
A tiny population of people now use the older browsers, and, being realistic, people who play
online games will have the tiny amount of knowledge required to download the proper SunVM.
Something simple might as well be 1.1 compliant, but, if your going for any amount of extravagance, I don't feel guilty by not limiting my code with a smaller set of features.
