Is this a bug in ImageIO? It gives inconsistent and nasty results

Question

Hi everyone
Here's a stumper that I have been having trouble with and finally have a test case to illustrate it. First of all, the code:
import java.awt.image.BufferedImage;
import java.io.File;
import java.net.URL;
import javax.imageio.ImageIO;
public class PicTest
    public static void main(String[] args) throws Exception
        BufferedImage buf1 = ImageIO.read(new URL("http://www.bestfoto.com/ArchivedPOTD/021606S.jpg"));
        BufferedImage buf2 = ImageIO.read(new URL("http://www.bestfoto.com/ArchivedPOTD/021606O.jpg"));
        ImageIO.write(buf1, "jpg", new File("C:/test1.jpg"));
        ImageIO.write(buf2, "jpg",  new File("C:/test2.jpg"));
}It's all very simple - we are pulling 2 jpgs from the net and writing them to 2 files. When you run it, test2.jpg is looking very nice. However, test1 is looking horrible and the color is completely off. Anyone know what's going on here? I've seen this on quite a few jpgs now and I'm thinking that there is either a bug in java's JPG codec or the incoming image is somehow corrupted. But, any web browser I try makes the image look fine.
What gives? Thanks!

Yes, I think this is a bug in java5 - it cannot write jpegs out because of a missing file in $JAVA_HOME/jre/lib/ccm. The file is called PYCC.pf.
I forgot that I copied this file from a previous version of the JDK, 1.4x. Maybe this is my problem? But if this file is causing the problem, then taking it out would break the jpeg writer completely.
Anyone have an idea about this?
Thanks
I tried you app in j2se 1.5 and came up with this
stack trace for both images:
C:\jexp>java PicTest
