> Key: PDFBOX-2015
> URL: https://issues.apache.org/jira/browse/PDFBOX-2015
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 1.8.7, 2.0.0
> Reporter: Tim Costermans
> Fix For: 1.8.8, 2.0.0
>
> Attachments: Word2010.pdf, XRefStm_not_updated.patch,
> modified_Word2010.pdf
>
>
> Word2010.pdf is the input pdf, I open the document with PDFBOX add a string
> to the pdf. In this case ‘Hello world!’.
> Afterwards I save the pdf.
> If I look at the content of the pdf before and after I modified it (using
> Notepad++) I see this:
> Word2010.pdf:
> Line 647: <</Size 18/Root 1 0 R/Info 7 0
> R/ID[<AE9AF29D5A22AE47B47C4DA29170BE64><AE9AF29D5A22AE47B47C4DA29170BE64>]
> /Prev 81972/XRefStm 81702>>
> modified_Word2010.pdf:
> Line 791: /XRefStm 81702
> XRefStm is not updated although the original pdf had multiple revisions that
> were merged into a new pdf document.
> A third party library we use defends on this XRefStm value and cannot open
> the pdf after it was modified. (Stack trace see previous msg)
> Any help would be much appreciated.
> Maruan:
> that’s a bug.
> Explanation: The original file uses what’s called a hybrid reference. That’s
> for compatibility with readers which do not support compressed reference
> streams. The file generated by PDFBox doesn’t use hybrid references any more
> but still contains the XRefStm info in the trailer dictionary.
