Maruan Sahyoun commented on PDFBOX-2503:
----------------------------------------
If the DocumentInformation meta data contains trailing NUL characters
everything is fine. For all others the trailing characters are taken into
account by Adobe Preflight as well as others and validated against the XMP
entry.
> false negative? 1: 7.2 : Error on MetaData, Producer present in the document
> catalog dictionary doesn't match with XMP information
