We get the following exception

Our Customers use Photoshop and sometimes wired Color Profiles appear in some Jpeg Files (photographers that use a Canon EOS and the MAC Version of Photoshop CS3)
Some Sun JREs sometimes crash with this broken jpeg headers. I found a short java solution to fix it. See below
The trick is to read the jpeg as a stream and not with ImageIo.ImageReader.read ....

Short FIX
private static String getFormatName (Object o) {
try {
// Create an image input stream on the image
ImageInputStream iis = ImageIO.createImageInputStream (o);

  // Find all image readers that recognize the image format
  Iterator iter = ImageIO.getImageReaders (iis);

  if (!iter.hasNext ())

    // No readers found
    return null;

  // Use the first reader
  ImageReader reader = ( ImageReader ) iter.next ();

  // Close stream
  iis.close ();

  // Return the format name
  return reader.getFormatName ();
} catch (IOException e) {}

// The image could not be read
return null;

}

USE:
String imageFormat = getFormatName (imageFile);

  if (imageFormat.equalsIgnoreCase (\"JPEG\")) {
    FileInputStream input = new FileInputStream(imageFile);
    JPEGImageDecoder decoder = JPEGCodec.createJPEGDecoder (input);
    image = decoder.decodeAsBufferedImage ();
    input.close();
  } else
    image = ImageIO.read (imageFile);

Look there i found this code: http://www.exampledepot.com/egs/javax.imageio/DiscType.html

Interesting !

Noted on my TODO list. I'll work on this one, when I finish my current task.
