Either you know about a way to use a Graphics/Graphics2D object that
I've never seen, or you are trying to use a Graphics2D object in a way
that it was never intended to support.

Could you explain what you are trying to accomplish? Maybe there's a
better way to do it.

In the meantime, have you tried removing the paintComponent() method
entirely and just putting this in the constructor:

setBackground(Color.BLUE);

?
