if I only could find where I read that for J2SE (>=1.2?) you always have 
a Graphics2D instance. I swear I have read it once.

It's true, I never think twice before casting a Graphics to Graphics2D. 
This works in all places where you can get such an instance (e.g. 
Image.getGraphics(), certain printing related classes).
