Description
The PDF in question displays a black image on the page, obfuscating the black text that is drawn above it. In our rendering core the JPEG image is detected as grey encoded. My first guess is that this is incorrect.
This issue is complicated by the the fact that our current JPEG support is handle by a now deprecated and removed library in JDK 1.7. As a result we'll have to look at this issue using an alternative image library.

Reworked how we handle images that enocded with JPEG_ENC_GRAY. Applying the colour model brings out the colour for lake of a better word.

The black image rendered by ICEpdf is a jpeg using the separation colour space. The JPEG detection code tries encoding the image using deviceGray which I don't think is correct in this case. There is no masking taking place.
Further investigation is needed.
