Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)


FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
jai_imageio-1_0-rc-lib-windows-i586.zip

A DESCRIPTION OF THE PROBLEM :
When applying a java.awt.image.LookupOp or java.awt.image.RescaleOp on a JPEG image loaded with javax.imageio.ImageIO the result has the wrong colors or throws eM-^^xceptions in native code. The behaviour seems to depend on the ImageReader used. For some cases it helps to create a destination image before calling filter instead of relying on LookupOp.createCompatibleDestImage. The problems do not arise with images loaded via com.sun.image.codec.jpeg.JPEGImageDecoder.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the provided case and run it. Make sure the demo/jfc/Java2D/Java2Demo.jar is in the CLASSPATH since the JPEG picture is taken from this JAR.

The program displays the show the image twice. The image on the left side should show the correct image, the one on the right is wrong.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Both images should be the same. This is the case if you comment in (4) and comment out (5) in the source code of the test case.
ACTUAL -
In the provided version of the test case the right image is tinted blue.

If you comment out (2) and comment in (3) the the source code the program fails with the exception given below.

If you now comment out (1) the exception is avoided but the rescaled image has totally wrong (psychodelic) colors.

CUSTOMER SUBMITTED WORKAROUND :
Load images with com.sun.image.codec.jpeg.JPEGImageDecoder.
Give a destination image when calling filter() [does not work for all problems].
