        Description

        FULL PRODUCT VERSION :
        java version "1.8.0_40"
        Java(TM) SE Runtime Environment (build 1.8.0_40-b26)
        Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)

        A DESCRIPTION OF THE PROBLEM :
        Create a child raster by createWritableChild with an x-offset and contains the bottom-right pixel. Then AffineTransformOp filter produce an ImagingOpException.

        If x-offset is 0 or the child raster doesn't contains the bottom-right pixel, the filter works well.
