Andreas Lehmkühler commented on PDFBOX-3888:
--------------------------------------------
I've fixed the issue by simply adding a loop. Most likely such calls of read()
should read all needed bytes, but it looks like this is only true if a small
amount of bytes is needed. In the ShowSignature example PDFBox has to read
33318 bytes and that isn't done in one step therefore a loop is needed. Saying
that, IMHO the implementation of BaseParser.checkForEndOfString() should be
safe as only 3 bytes are needed

> The COSParser contains a lot of stuff which is more or less hard to
> understand/maintain. I'm going to refactor some of the code as follows
> - separate the bruteforce stuff maybe in its own class
> - separate the parsing of the xref data maybe in its own class
> - lay the foundation for the on demand parser
