Is there a 100% Java alternative to ImageIO for reading JPEG files?

Question

We are using Java2D to resize photos uploaded to our website, but we run into an issue (a seemingly old one, cf.: http://forums.sun.com/thread.jspa?threadID=5425569) - a few

I faced the same issue. I was reluctant to use JAI as it is outdated but it looks like it's the shortest solution.

This code converts an InputStream to a BufferedImage, using sun's ImageIO (fast) or in the few cases where this problem occur, using JAI:

public static BufferedImage read(InputStream is) throws IOException {
    try {
        // We try it with ImageIO
        return ImageIO.read(ImageIO.createImageInputStream(is));
    } catch (CMMException ex) {
        // If we failed...
        // We reset the inputStream (start from the beginning)
        is.reset();
        // And use JAI
        return JAI.create("stream", SeekableStream.wrapInputStream(is, true)).getAsBufferedImage();
    }
}
