>  Ihave PDF file which was signed by some other application. When I try to sign it with PDFbox, previous revision is damaged. I have discussion at stackoverflow, with Michael Klink.

> when we see some changes merely was structural. Some changes was just rounding problem   - ISSUE 1778.
> When I test,  problem of damaged signature was  caused from structural change [when there must be direct reference, there was indirect reference and etc..]
> So we solve that problem. I will upload damaged PDF document,  fixed pdf, and the patch too.
