Timo Boehme commented on PDFBOX-1920:
-------------------------------------
As I told you 'rePDF', 'cutepdf' etc. are no PDFBox tools, are not known in the
PDFBox environment and thus cannot be supported, commented etc. PDFBox is
merely a library for handling PDFs and you use a 3rd party (?) software which
itself uses PDFBox.
The problem you face only happens with broken PDFs where a stream within the
PDF cannot be correctly parsed and PDFBox tries to 'repair' it. For this the
stream has to be re-parsed and in order to do this it has to be filled in the
push back buffer. If this buffer is too small this action fails. So you have to
specify the buffer size with the mentioned system property. If you do not know
how to do this please ask the vendor of the software you are using.
