-------------------------------------------------------------
I have no idea how to properly handle entries that are longer than 2 bytes.
But I think it is better to skip them and not throw Exception there. Just
logging of warning or error should be fine.
If somebody tries to render (to image) such PDF now it will fail.
I suggest to remove that Exception so PDF will be rendered. Rendered image will
be most likely ok. Maybe some char will not be drawn.

>
> I have PDF that has CMap entry consisting of 4 bytes. It is just one entry
> with that size, other entries have 2-bytes.
> Adobe reader has no problems with that, PDFBox throws Exception.
> I think this Exception should not be thrown. It should be skipped or
> truncated tu 2 bytes and write warning to log.
