InputStream in = ClipImage.class.getResourceAsStream(imgFile);
JPEGImageDecoder decoder = JPEGDecoder.createJPEGDecoder(in);
final BufferedImage bufferedImage = decoder.decodeAsBufferedImage();
Only the jai-imageio project which contained JPEGImageDecoder did not have any JPEGDecoder in it. So it was back to search for JPEGDecoder and there were very few hits. The GNU classpath project had a JPEGDecoder and after getting all the files, it became evident that it wasn't quite the same as the decoder I wanted. The documentation was also scarce and by then I was able to get the color I wanted by running the image editor on my laptop.
Moral of the story: Don't go on a wild goose chase
