----------------------------------------
Wiley Fuller, do you have some example file that you can attach?
I'm using incremental updates all the time with pdfbox and can't find any issue
with the latest revision (last update a minute ago).

> The academic repository JStor makes papers available via PDF format. The

> Content creator: JstorPdfGenerator v1.0
> PDF producer: iText 2.0.6 (by lowagie.com)
> These PDFs open fine in Acrobat, Preview, FoxIt, etc., but they throw an
> exception in PDFBox:
> Exception in thread "main" java.io.IOException: Error: Expected to read
> '%%EOF' instead started reading '1'

> I traced through the code, and it appears that PDFBox rejects these because
> they contain a 'startxref' that is not followed by a %%EOF two lines later:

> startxref

> 1 0 obj

> Here's a small patch that will accept files that are missing the EOF after
> the startxref:
