Tilman Hausherr updated PDFBOX-2250:
------------------------------------
Attachment: PDFBOX-2250-229205.pdf
The attached file PDFBOX-2250-229205.pdf has an NPE, resulting from "Cannot add
trailer because XRef start was not signalled". Upcoming fix will slightly
modify my previous fix (1619255) related to empty xref tables, so that
curXrefTrailerObj isn't null but empty instead.
> 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.
