The following small program (utilising the attached image) crashes for me on
Solaris SPARC with (at least) JDK 1.4.2, 1.5 and JDK 6 :

import javax.imageio.*;
import java.awt.image.*;

public class FilterCrash {

    public static void main(String s[]) throws Exception {

        BufferedImage bi = ImageIO.read(new java.io.File("bld.jpg"));
        int iw = bi.getWidth(null);
        int ih = bi.getHeight(null);
        BufferedImage bo = new BufferedImage(iw, ih, bi.getType());
        RescaleOp rop = new RescaleOp(1.1f, 20.0f, null);
        rop.filter(bi, bo);
    }
}
