COSVisitorException: The handle is invalid

[Alan Thomas]

Hi.  When I save a PDF document in my application, I get a COSVisitorException: 
"The handle is invalid".

        However, I do not see anything wrong with it.  I show the error, the 
string I am giving the PDDocument.save() method, and the code that attempts to 
save the file.

        Any idea what I am doing wrong?                Thanks, Alan
