Note, I do use general path and drawshape:
private void drawCircleBar(Graphics g, int pullToTheLeftPixels, int
angleToStartOn, int angleToEndOn, int colour)
{
GeneralPath pathStatic = new GeneralPath();//these should not be
made each time but had repaint issues when I did, see

if (stroke == null)

stroke = new Stroke(strokeWidth, Stroke.CAP_BUTT,
Stroke.JOIN_ROUND, 1f);
}
