> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing
> Affects Versions: 1.6.0
> Reporter: Timo Boehme

> Priority: Minor
> Fix For: 1.7.0

>
> Currently object offsets are stored as integer (32 bit). However the PDF
> specification does not limit a PDF document to 2GB. The only restriction is
> the XREF table which supports 10 digit values for object offsets. Thus we
> could have offsets >2GB (<10GB). The attached patch changes all locations (as
> far as I could find them) dealing with object offsets to long type.
> Since this is a rather small change which should not have greater
> performance/space impact I recommend to include it. Otherwise we would have
> to include checks that the parsed file is smaller then Integer.MAX_VALUE.
