Hi, thanks for the reply. These are new files, ie, i'm creating them from a memory structure using Apache FOP (legacy code), PDFBox was added recently to post-process the documents in order to make them read-only .
The crucial point is that all of the pdfs (200-300 per day) are created and locked down in the same way and yet in the last couple of months I've had two instances of a file being password protected at the user level.

There's a method to remove all encryption (I think it's in PDDocument, if I recall correctly). If you start with that method, you can be certain that any old encryption was removed, and all that will remain is what is in your code below.
