Juraj Lonc commented on PDFBOX-2074:
------------------------------------
I am curious whether Adobe Reader ignores such entries (entries are invalid) or
processes them (entries are valid).
> 4-bytes CMap entry causes exception

> 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.
