Another problem is that the "highest" certificate does not have an URL
to download the root. So I can't get that one.
A solution would be that you change the code so that you keep a set of
certificates that you trust and look there when one is missing.

Hi,
Yeah, the log output is confusing, I'll improve it slightly to output
what it was searching for. I ran ShowSignature and it's the root
certificate that is missing in the chain.

Hi all, I'm trying to use the example AddValidationInformation[1]
class to add LTV to an existing signed PDF. I've tried with a signed
PDF of my own, and a sample GlobalSign[2] PDF.
In both cases, I get the same error, and a 0kb PDF generated. Logs[4]
are at the bottom of this post.
Steps to reproduce:
1. git clone g...@github.com:apache/pdfbox.git
2. cd pdfbox/examples
3. mvn clean install
4. Open pdfbox project in IntelliJ
5. Run AddValidationInformation class, with the downloaded
GlobalSign pdf as a program argument
The GlobalSign PDF has LTV enabled already, but I get the same error
on my own document which doesn't have LTV. For my own document, I can
enable LTV via Adobe Acrobat's UI[3], which makes me think the
document itself is fine.
Can anybody shed some light on why this might be happening? The
recursive traverseChain() method seems to spin until it hits the end
of the certificate chain, and continues to look for an issuer cert.
Thanks so much, I appreciate your help! Let me know if you need any
more information and I'll do my best to provide it.
