ImageView doesn't load Image from style sheet

In the early access B25 release the following code

        ImageView img = new ImageView();
        img.getStyleClass().add("expand-image");

with a CSS style sheet of

        .expand-image
        {
            -fx-image: url("images/maximize.jpeg");
        }

would load the given image from the style sheet as the Image field of the ImageView.

In the beta this no longer works.
