      Description

        A TYPE_CUSTOM BufferedImage with the same SampleModel, ColorModel and pixel data as a TYPE_BYTE_GRAY BufferedImage is rendered differently (it shows up a lighter gray). A test case that demonstrates this is attached.

        The Java Advanced Imaging API (JAI) uses a custom subclass of WritableRaster in some instances, which when converted to a BufferedImage, results in a TYPE_CUSTOM BufferedImage, causing lighter rendering to be noticed by customers. This issue was reported by a JAI customer:
