Cannot draw into BufferedImage of TYPE_BYTE_BINARY using Graphics2D

When BufferedImage of type TYPE_BYTE_BINARY is created and Graphics2D is obtained from the image, drawing shapes into it by calling fill method doesn't change any of the bits in the buffer. This doesn't happen when JDK 1.3.1 or JDK 1.3 is used. Please try the following to recreate:

    Shape s2 = new Rectangle(0, 0, 5, 5);
    BufferedImage bi = new BufferedImage(5, 5,
                            BufferedImage.TYPE_BYTE_BINARY);
    Graphics2D g2d = bi.createGraphics();
    g2d.fill(s2);
    int[] pixels0 = bi.getData().getPixels(0, 0, 5, 5, (int[])null);
    for (int i = 0; i < pixels0.length; i++)
      System.out.println(pixels0[i]);
