[Bug awt/24701] AreaAveragingScaleFilter is unimplemented

Here is a code fragment demonstrating the problem:

/* testImageScale.java */
import java.awt.Image;
import java.awt.image.BufferedImage;

class testImageScale {
    public static void main(String args[]) {
        System.out.println("Creating 20x20 BufferedImage"); 
        BufferedImage foo =
            new BufferedImage(20, 20, BufferedImage.TYPE_INT_RGB);
        System.out.println("Creating 10x10 image using SCALE_AREA_AVERAGING");
        Image bar = foo.getScaledInstance(10, 10, Image.SCALE_AREA_AVERAGING);
        if (bar == foo) System.exit(1);
    }
}

When I run it with jamvm, I get this output:

Creating 20x20 BufferedImage
Creating 10x10 image using SCALE_AREA_AVERAGING
java.lang.ArrayIndexOutOfBoundsException: 100

(and then jamvm hangs. :( ))
