Thank you people behind i...@1t3xt.info :)
There is an application reproducing the problem... I hope that someone could
find the source of the problem. This arrived with different PDF source
(printed with pdfFractory, OpenOffice, ...) for the original PDF (will be
PDF_A).
*To use this application, just place a PDF named "PDF_A.pdf" at the base of
the project. Need library PDFBox and iText.*
Thank you.
