[jira] [Commented] (PDFBOX-1872) PDMetadata.exportXMPMetadata fails when Metadata has encrypted stream

["Pat Hickey (JIRA)" <ji...@apache.org>]

Pat Hickey commented on PDFBOX-1872:
------------------------------------

Forget that workaround - I was looking at the wrong document. It ends up with the encrypted data, as well.

>          Components: JempBox, PDModel
>    Affects Versions: 1.8.3

>            Reporter: Pat Hickey
>            Priority: Minor

> My guess is that PDDocumentCatalog.getMetadata() gives PDMetadata the raw stream, instead of the filtered one. Then PDMetadata.exportXMPMetadata() calls XMPMetadata.load(), which cannot parse the encrypted stream.  
> As a workaround, this seems to do the trick (where document is the PDDocument loaded from the PDF):
>     String content = null;
>     COSStream md = (COSStream)document.getDocument().getCatalog().getDictionaryObject( COSName.METADATA );
>     if ( md != null ) {
>         PDStream pd = new PDStream( md );
>         content = pd.getInputStreamAsString();
>     }
