There is a suspicious to the Math.ceil method with integer argument. Calling Math.ceil with integer argument is useless - it will just return the same passed value.

javax.swing.text.html.StyleSheet.ListPainter#drawShape

    int y = Math.max(ay, ay + (int)Math.ceil(ah/2));

'ah' is 'int'

Seems we should remove it.
