FULL PRODUCT VERSION :
1.6.0_05-b13
ADDITIONAL OS VERSION INFORMATION :
Windows XP Professional 5.1.2600 Service Pack 2 Build 2600
EXTRA RELEVANT SYSTEM CONFIGURATION :
AMD Athlon 64 2Ghz 3800x2
ATI X300SE 128MB VRAM video card
2GB of RAM
A DESCRIPTION OF THE PROBLEM :
In my image resize/compress code I'm trying to save an image along with its Exif metadata but for some images the image becomes red. I'm using com.sun.imageio.plugins.jpeg.JPEGImageReader and com.sun.imageio.plugins.jpeg.JPEGImageWriter. The image type is TYPE_3BYTE_BGR
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Load the image as in the code provided
2. Save it
3. You will see the result by looking at the image
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I was expecting the image to look the same not to look red.
ACTUAL -
The image is scaled but it's red.
REPRODUCIBILITY :
This bug can be reproduced always.
