FULL PRODUCT VERSION :
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
Reading a jpg image and writing it to disk results in in "pink" image if it is saved with its original metadata.
Saving it the same way without metadata results in a good image.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Get the sample image from http://www.cuillerdier.net/PinkBug.JPG
Copy the picture and the test case in the same directory
Compile and run
Check the resulting images "PinkBug WithMetadata.jpg" and "PinkBug NoMetadata.jpg"

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
"PinkBug WithMetadata.jpg" looks pink but "PinkBug NoMetadata.jpg" look like the original file.

REPRODUCIBILITY :
This bug can be reproduced rarely.
