Tilman Hausherr updated PDFBOX-2250:
------------------------------------
Attachment: 055794.pdf
Wow this fixes many offset problems.
However with 055794.pdf I get this:
Exception in thread "main" java.io.IOException: XREF for 10:0 points to wrong
object: 0:0
Indeed: offset 11 points to "0 0 obj"... the correct offset 10 would have
pointed to "10 0 obj". Could this be treated like a "not found" and then
searched?

> 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.
