[jira] [Commented] (PDFBOX-2903) ClassCastException at PDFParser:667

["Shaun Kenny (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-2903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14640699#comment-14640699 ] 

Shaun Kenny commented on PDFBOX-2903:
-------------------------------------

Locally, I've replaced the code noted in the issue description with the following, and I am able to merge my PDF input streams without error:

COSBase baseObject = (COSBase)strmObj.getItem( COSName.TYPE );
COSName objectType = null;
if (baseObject instanceof COSString) {
    String baseObjectValue = ((COSString)baseObject).getString();
    objectType = COSName.getPDFName(baseObjectValue);
}
else
{
    objectType = (COSName)baseObject;
}

Unfortunately I am unable to attach the PDF that is causing the problem as it contains sensitive information.

> from "skenny" in the user mailing list:
> I'm using PDFMergerUtility to merge a number of PDF input streams and write
> them to an HTTP response output stream.  One of the PDFs is failing at line
> 667 in PDFParser:
> {code}
>     final COSName objectType = (COSName)strmObj.getItem( COSName.TYPE );
> {code}
> The result of getItem(COSName.TYPE) is a COSString (value "Metadata") and
> not a COSName.
