A DESCRIPTION OF THE PROBLEM :
JPEGFlip.java has a portability issue. It uses Sun-specific classes to load and store JPEGs, instead of using the standard imageio framework.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
$ grep import src/java2d/demos/Images/JPEGFlip.java | grep sun



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
$ grep import src/java2d/demos/Images/JPEGFlip.java | grep sun

and no output. ;)
ACTUAL -
$ grep import src/java2d/demos/Images/JPEGFlip.java | grep sun
import com.sun.image.codec.jpeg.*;


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Here is a fix for the source code as a unified diff:

I wish there was a way to attach patches to this thing, rather than hoping that the browser doesn't munge them.
