[OpenJDK 2D-Dev] [8] Review request for 8023565: JPG causes javax.imageio.IIOException: ICC APP2 encoutered without prior JFIF!

[anton nashatyrev]

Hello,
     could you please review the following fix:

fix: http://cr.openjdk.java.net/~alitvinov/8023565/webrev.00 
<http://cr.openjdk.java.net/%7Ealitvinov/8023565/webrev.00>
bug: http://bugs.sun.com/view_bug.do?bug_id=8023565 (the bug is not 
still replicated here so please use the internal jbs if available)

     Problem description: if the JPEG file doesn't contain the JFIF flag 
tag, but contain the ICC_PROFILE tag then reading its metadata via 
ImageIO causes exception: javax.imageio.IIOException: ICC APP2 
encoutered without prior JFIF!

     Fix description: Though it looks like the image was created 
incorrectly (no JFIF flag, but the JFIF extension tag exists), the image 
format is not formally corrupted. imageio Jpeg decoder should ignore the 
implied tag nature (ICC profile) and just treat it as an application 
specific tag.

Thanks!
Anton.
