I suspect though that in the case of some of the worse issues such as font rendering and graphical fidelity in general, if some solution is put into place for either Java 6 or Java 7 implementations it will probably be used in both. The Java specification doesn't concretely specify how things have to look graphically or what the graphical performance must be like.
The things I came across on the internet regarding text rendering in Java implied that the solutions put in place so far are known full well not to be the best but resources are limited and there is already so many other things to do that this issue is probably not going to get the same attention. I wonder if some of the text / font rendering couldn't be written in Java using the graphics pipeline to perform the drawing. I suppose whether it is implemented in Java or using a native library probably isn't so much of an issue compared with it being easier to reuse some existing implementation of text rendering rather than write a new one, especially to get things done quickly.
