--------------------------------------------------------------
I've taken a look and it looks like is a duplicate of PDFBOX-1955, the cause in
both cases is PDDeviceGray's RGB conversion. Does the fix for PDFBOX-1955
resolve this?

> In testCreateLosslessFromImageRGB() I create a grayscale image, and in
> LosslessFactory.createFromImage() I save it as a grayscale image (that part
> is currently disabled, search and enable the part with
> BufferedImage.TYPE_BYTE_GRAY. When this is enabled,
> testCreateLosslessFromImageRGB() fails the identity test. The expected and
> the actual images are attached. I traced this effect to
> PDColorSpace.toRGBImageAWT(), where I saved the "src" and the "dest" image
> and got two different ones. But even the first one is already different to
> the grayscale image I created in the test.
> The two attached file pairs were created by writing the BufferedImage src and
> dst in PDColorSpace.toRGBImageAWT().
