Daniele Ribaudo updated PDFBOX-5717:
------------------------------------
Description:
I tried to apply a digital signature to the attached PDF using the method
PDDocument.saveIncrementalForExternalSigning in the release 3.0.0 of PDFBox but
a NPE is thrown every time.
The same action executed on a 2.0.x release is successfully completed.
Here you are a snipped code to reproduce the error:
{{PDDocument document = Loader.loadPDF(new
File("Cryptomathic_White_Paper_-_eIDAS_Compliant_Remote_eSigning.pdf"));}}
{{document.addSignature(new PDSignature(), new SignatureOptions());}}
{{ExternalSigningSupport externalSigning =
document.saveIncrementalForExternalSigning(new ByteArrayOutputStream());}}
