On Windows, anti-aliased JLabel and JButton are not useable because
their size is initialized with the length of not a-a text, which
is different of the length of a-a text (a ... appears).

Similarly, selecting text in a a-a JTextComponent shows a colored
background that does not cover the proper range of selected text.

This is somewhat related to bug 4233886, but this one is closed.

Sample code :

import javax.swing.*;
import java.awt.*;

class AA extends JFrame {
  public static void main(String[] s) {
    new AA();
  }
  AA() {
    getContentPane().setLayout(new FlowLayout());
    getContentPane().add(new AAText("a long long long line of text"));
    getContentPane().add(new AAButton("button"));
    pack();
    show();
  }
}

class AAText extends JTextArea {
  AAText(String s) {
    super(s, 4, 40);
  }
  public void paintComponent(Graphics g) {
     ((Graphics2D)g).setRenderingHint
      (RenderingHints.KEY_ANTIALIASING,
       RenderingHints.VALUE_ANTIALIAS_ON);
    super.paintComponent(g);
  }
}

class AAButton extends JButton {
  AAButton(String s) {
    super(s);
  }
  public void paintComponent(Graphics g) {
     ((Graphics2D)g).setRenderingHint
      (RenderingHints.KEY_ANTIALIASING,
       RenderingHints.VALUE_ANTIALIAS_ON);
    super.paintComponent(g);
  }
}
