Why are my RenderingHints keys, when applied to a Graphics2D object, not being honored?

Question

When drawing various things using a Graphics2D object and BasicStroke at 1.0f, I can't seem to get the g2d object to honor my RenderingHints settings. Specifically the *KEY_ANTIALIASING* set to *VALUE_ANTIALIAS_ON*.

public void paint(Graphics g) {
    Graphics2D g2d = (Graphics2D)g;

    g2d.setStroke(new BasicStroke(1.0f));
    g2d.setRenderingHint(
     RenderingHints.KEY_ANTIALIASING,
     RenderingHints.VALUE_ANTIALIAS_ON
    );

    // draw stuff...
}

Are there other keys I should be using? Am I not applying the keys in the appropriate place? Using it the way described above results in normal, pixelated shapes being drawn.

If you are stroking (as it looks like you are from your snippet), you might want to also try:

g2.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
