JfreeChart: drawing an rectangle annotation on a candlestick chart doesnt apply the given width and height settings

Question

I am trying to plot an Rectangle annotation at the given X,Y coordinates. It does actually try to draw something at the coordninates as you can see in the image. But for some reason it just wont apply the set width and height. So i just get a small vertical line. Any help would be greatly appreciated!
