Specification for
public int *getIndexAtPoint*(Point p) says:

Given a point in local coordinates, return the zero-based index of the
character under that Point. If the point is invalid, this method returns
-1. Note: the AbstractButton must have a valid size (e.g. have been
added to a parent container whose ancestor container is a valid
top-level window) for this method to be able to return a meaningful value.

But behaviour of this method for JButton and JLable seems to be strange.
Run the following code on b86:
    public void test() {
        final JFrame f = new JFrame();
        final JButton but = new JButton();
        but.setText("<html><body><p>Test</p></body></html>");
        try {
            SwingUtilities.invokeAndWait(new Runnable() {
                public void run() {
                    f.setSize(300, 300);
                    f.setVisible(true);
                    f.getContentPane().add(but);
            } } );

            AccessibleText c =
                but.getAccessibleContext().getAccessibleText();
            Point p;
            for(int y = 0; y < 2; y++) {
                for(int x = -5; x < 60; x++) {
                    p = new Point (x,y);
                    System.out.println("Point = " + p + "; " + c.getIndexAtPoint(p)) ;
                }
            }
        } catch (Exception e) {
            //todo
        } finally {
            f.dispose();
        }
    }
