FULL PRODUCT VERSION :
java version "1.4.2-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-beta-b19)
Java HotSpot(TM) Client VM (build 1.4.2-beta-b19, mixed mode)


FULL OS VERSION :
Microsoft Windows XP [Version 5.1.2600]


A DESCRIPTION OF THE PROBLEM :
Drawing Custom RenderedImage types fails when scaling transform is applied. After setting up a RenderedImage using a PixelInterleavedSampleModel, any drawRenderedImage using an AffineTransform scale transform other than 1.0 results in java.awt.image.ImagingOpException: Unable to transform src image
that seems to be comming from ImagingLib.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
  To draw the RenderedImage
ACTUAL -
Exception occured and no renderedImage drawn

see source code test case.
