twice
[ https://issues.apache.org/jira/browse/PDFBOX-4261?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

> Project: PDFBox
> Issue Type: Bug
> Components: Signing
> Affects Versions: 1.8.15
> Reporter: Claudio Tortorelli
> Priority: Major
> Fix For: 1.8.16

>
> A customer sent us a pdf that has this problem: when it is signed twice by *pdfbox 1.8.x* the second signature invalidates the first one.
> If we apply the same procedure using *pdfbox 2.0.x* the problem doesn't occur, but the customer required java 1.5 so we can't switch to the new version in this case.
> For +privacy purposes+ we had anonymized the original PDF file by editing 3 stream inside the pdf, without altering the original structure. So the file "92752146_noSign_anonymous.pdf" you can find in attachement has not the original text/image streams, but reproduces the problem as the original one.
> Thank you in advance
