              I've had a good look at this one and I'm pretty sure I've found the problem. The PDF in question uses optional content groups, well sort of, there setup but not 100% configured correctly. When itext touches the files it drops the main OCProperties dictionary from the /OCProperties from the document catalog and as a result ICEpdf treats the layers as invisible.

              My guess is that Acrobat ignores the content group data in the content stream if the /OCProperties entry is missing. If we follow this assumption the PDF renders correctly.
