Andreas Lehmkühler commented on PDFBOX-2250:
--------------------------------------------
I've improved the xref repair mechanism and fixed the issue with the not found
object mentioned by Tilman (055794.pdf).
[~tilman] I had a look at 113223.pdf, but I can't find anby object which can be
found. Can you give me a pointer where to look?
*TODO*
- the xref repair algorithm simply searches for the nearest offset, which may
fail if more than one xref table is present
> Improve XRef self healing mechanism

> PDFBOX-1769 introduced a "self healing" mechanism to repair corrupt XRef
> offsets. But that one was just a starter and there remain a lot of issues to
> be solved. I'm planing to solve at least some of them.
> All fixes and improvements are targeting the non-sequential parser and I
> won't port those changes to the old parser.
