I just sent a message to jchempaint-devel that crossed yours in the mail.

All Java code since 1.2 uses Java2D.

For backwards compatibility, the paint(...) routine still takes a Graphics
object. But you can immediately cast this to be a Graphics2D object.

void paint(Graphics g) {
  Graphics2D g2d = (Graphics2D)g;
  ...
}


This is the proper way to do it as documented by Sun.

You can then use

 g2d.setRenderingHint(...)

to turn on antialiasing.
