FULL PRODUCT VERSION :
Java(TM) SE Runtime Environment (build 1.6.0_15-b03)
Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Windows Vista Home Premium Service Pack 1

A DESCRIPTION OF THE PROBLEM :
Pixel data from files read with imageIO appear to be incorrect when the images were previously saved using Photoshop and selecting either ICC Profile Adobe (1998) or sRGB IEC61966-2.1 in the Save As dialog box.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Save an image with Photoshop (Elements 5) and select either ICC Profile Adobe RGB (1998) or sRGB IEC61966-2.1. Use ImageIO to read the file and then read the pixel data to create a histogram.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Number of pixels for each level (0-255) should be accurate and if used to create a histogram, should match those displayed using Photoshop or GIMP, etc.
ACTUAL -
A few pixel levels are wrong.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error, just bad data.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Use either

java.awt.Toolkit.getDefaultToolkit().createImage(filename);

or

JAI.create("fileload", fileName).getAsBufferedImage();
