Description

Hello,

In the DSS framework, I try to retrieve the original document from a signed PDF. If the document before adding the signature finished with '%%EOF', it doesn't work. Actually, it only works if the document is finished  with a EOL character.

After some investigations, I found this line in the PDFBox project.

IMHO, the EOL shouldn't be added after the '%%EOF'. If we refer to the ISO 32000-1:2008 chapter 7.5.5 :

ISO 32000-1:2008

The last line of the file shall contain only the end-of-file marker, %%EOF.

When I do a saveIncremental, the data to be signed finishes with a EOL character.

So, I'm not able to retrieve exactly the same binaries. In some cases, it matches otherwise I have a EOL too much.

Could you have a look ? 

Thanks in advance
