Comment (by Balling):

 "What is funny is that Kakadu encoded lossy images are better decoded by
 Kakadu itself, then openjpeg, then jpeg 2000, while openjpeg encoded lossy
 images are better decoded with jpeg2000! Very strange."

 Also, I suppose it will not be fixed, JPEG 2000 parser is there for a
 reason.
