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

https://github.com/openjdk/jdk/blob/d10afa26e5c59475e49b353ed34e8e85d0615d92/src/java.desktop/macosx/classes/com/apple/laf/AquaProgressBarUI.java#L259

com.apple.laf.AquaProgressBarUI#getStringPlacement

    return new Point(x + Math.round(width / 2 - stringWidth / 2), y + ((height + fontSizer.getAscent() - fontSizer.getLeading() - fontSizer.getDescent()) / 2) - 1);

'width' and 'stringWidth' are 'int'

Seems we should remove it.
