[OpenJDK 2D-Dev] ImageIO.read(jpeg): different RGB from OpenJDK and Oracle Java

[Bill Ross]

If this is the only diff between the Java's involved here, it is 
interesting that it is sufficient to switch photo pair distances from 
Group 2 to Group 3 in the interpretation of the histograms as 
coordinates in Poincare spherical space.
