I am using following code instead of ImageIO.read() as we have older Java
version and it gives dark image as specified in Java bug
(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6372769). It has been
working fine till now, however recently it started throwing exception for
certain photos -

java.lang.IllegalArgumentException: Invalid ICC Profile Data

When I searched, I found that it is yet another Java bug -http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6404011

We **cannot** chnage the Java version on our server. So I have to figure out
workaround for the following code --

   public static BufferedImage read(File file) throws IOException {
        BufferedImage image = null;
        ImageInputStream iis = ImageIO.createImageInputStream(file);
        if (iis == null) {
            throw new IOException("File not found");
        }
        Iterator<ImageReader> iir = ImageIO.getImageReaders(iis);
        boolean looking = true;
        ImageReader reader = null;
        ImageReadParam param = null;
        while(looking && iir.hasNext()) {
            reader = iir.next();
            reader.setInput(iis);
            param = reader.getDefaultReadParam();
            Iterator it = reader.getImageTypes(0); //this line throws
exception java.lang.IllegalArgumentException: Invalid ICC Profile Data

            while (looking && it.hasNext()) {
                ImageTypeSpecifier type = (ImageTypeSpecifier) it.next();
                ColorSpace cs = type.getColorModel().getColorSpace();
                if ( cs.isCS_sRGB() ) {
                    param.setDestinationType(type);
                    looking = false;
                }
                if ( cs.getType() != ColorSpace.TYPE_RGB ) {
                    looking = false;
                }
            }
        }
        if (reader != null) {
            image = reader.read(0, param);
        }
        return image;
    }}How can I rewrite the code to do what I desire (read an image) by ignoring

ti sexception??? I tried to enclose the Exption throwing line & loop below
that in try-catch blok, but for soome weird reason, it simply hangs the JVM
and I am lost -- how can I fix this? I am not an image expert and hence
finiding it difficult to decide how to come up with a workaround!!Any help,
pointers would be highly appreciated!!TIA,- Manish


It seems that you found the bug details, but failed to read the info.
The workaround is shown in the bottom of http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6404011
