I'm trying to open this PDF File to automate form filling: DA1059
PDFtk, PDFBox, Chrome's PDF Viewer, and the Mac OSX preview app all fail to open the PDF.
However, Adobe Reader or Acrobat successfully open the PDF without prompting for a password.
PDFtk errors out with:
$ pdftk da1059.pdf dump_data_fields
Error: Failed to open PDF file:
da1059.pdf
OWNER PASSWORD REQUIRED, but not given (or incorrect)
Done. Input errors, so no output created.
PDFBox errors out with:
$ java -jar pdfbox-app-1.8.9.jar ExtractText da1059.pdf

Tilman Hausherr pointed out it's an XFA form. There's a couple of related questions on Stack Overflow:
I started a minimal working example at https://github.com/jschaf/pdfxfa.
Not Supported
Working with XFA and certified forms in PDFBox depends on incremental update which is currently not supported. See PDFBOX-2859 Support for Incremental Update.
