-----------------------------------------

Hi, 

I don't know if this helps at all, but I noticed that the described problem is caused by the document's being encrypted with an owner password. If (somehow) one was able to remove the protection, then the saved document would be an exact copy of the original. 

So, I guess it is good as it is, so that <PDDocument.save(...)> won't decrypt a password protected document. (One could have invoked something like <doc.openProtection(new StandardDecryptionMaterial("<owner_pass>"))> before saving the document in order to decrypt it). 
On the other hand, I think it would be "nice", if the user would be somehow informed (by means of an Exception ??), that he is trying to save an encrypted document, without decrypting it first (unless there are any cases where it is desirable for the user to do so - nothing crosses my mind, but being new to all this PDF stuff, that doesn't tell much). 

Well, that was it. 
I hope my remarks will be of some use to someone more knowledgeable !

> I have a file (attached) that when loaded with PDocument.load and then saved to another location simply saves as a blank PDF.  The number of pages is correct, but when opened in Acrobat, all the page names are corrupted and the pages are blank.
> Here's the code:
>         PDDocument doc = PDDocument.load("/home/jnankin/Desktop/in.pdf");
>         doc.save("/home/jnankin/Desktop/out.pdf");
>         doc.close();
> Please advise.
