Hi,
Please try loadNonSeq(file,null).
Nevertheless you are correct, it doesn't work with the "old" parser.
What's even weirder is that there seem to be several of these i-9 forms.
The first one from PDFBOX-2469 works, the one you attached (it landed in
moderation) doesn't.
And then there's the second one in PDFBOX-2469, that doesn't work
either. The text at the end of PDFBOX-2469 is somewhat unclear, but it
seems we didn't solve them all.

Hi team,
I see that the PDFBox has staged out new release 1.8.8, so I just try
to use the new version.
When I decrypt a PDF file which is decrypted, I got the exception bellow:
org.apache.pdfbox.exceptions.WrappedIOException

And my code is :
PDDocument doc = PDDocument.load(originFile);
if (doc.isEncrypted())
{
try
{
DecryptionMaterial dm = new StandardDecryptionMaterial("");
doc.openProtection(dm);
doc.setAllSecurityToBeRemoved(true);
}
catch (Exception cre) {
cre.printStackTrace();
}
}
I use the attachment file to do the operation.
I found this
http://stackoverflow.com/questions/26963718/badpaddingexception-when-decrypting-with-pdfbox in
stackoverflow.
I tried by the advices and it still not work.
So I post this email to you. Hope to get your answer.
Best wishes,
Barry
