FULL PRODUCT VERSION :
java version " 1.7.0_09 "
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) Client VM (build 23.5-b02, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
Color RGB(169,169,169) is converted to pink if AffineTransformOp::filter is called on an BufferedImage of type BufferedImage.TYPE_INT_ARGB.
This behavior is only present when AffineTransformOp.TYPE_NEAREST_NEIGHBOR is used and it did not happen on JDK 6.


REGRESSION. Last worked in version 6u31


REPRODUCIBILITY :
This bug can be reproduced always.
