No, I can't think of one, only a code change...
One might change the code of SecurityHandler.decryptStream(), to
identify meta streams that are not encrypted (they start with
"<?xpacket"), or to catch the exception that you got. I'll test this
tomorrow. In the meantime, please open an issue in JIRA
https://issues.apache.org/jira/browse/PDFBOX

Your file is incorrect: it is encrypted, the META data is unencrypted, but
EncryptMetadata is not set to false.

Hi there!
Using pdfbox-1.8.9, pdfbox-1.8.11, and pdfbox-2.0.0-RC3, I get the
error/trace shown below for the PDF at this web address. Same error using
PDFDebugger or Decrypt, or any other command-line too. Same error in my
code, using either the bottom-up or top-down parser.
Curiously, pdfbox-1.8.3 does not complain. (Not that I will use 1.8.3...)
Is this a known bug?
Tnx, Pat
