    could you please review the following fix:

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.
