------------------------------------------------------------------
The attached files PDFBOX-2250-229205.pdf and PDFBOX-2250-233566.pdf have an
NPE, resulting from "Cannot add trailer because XRef start was not signalled".
Upcoming fix (will run test suite first) will slightly modify my previous fix [
https://svn.apache.org/r1619255 ] related to empty xref tables, so that
curXrefTrailerObj isn't null but empty instead.

> 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.
