PDFBOX-4307: check object type before casting to COSDictionary in
PDDocumentCatalog.getDocumentOutline
> ClassCastException in PDDocumentCatalog.getDocumentOutline if 'outlines' is
> not a dictionary
> --------------------------------------------------------------------------------------------

> Key: PDFBOX-4307
> URL: https://issues.apache.org/jira/browse/PDFBOX-4307
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 2.0.11, 3.0.0 PDFBox
> Reporter: Timo Boehme
> Assignee: Timo Boehme
> Priority: Minor
>
> In PDDocumentOutline.getDocumentOutline() the 'outline' is read as dictionary
> object and directly cast to COSDictionary. Normally this is ok as it should
> be a dictionary. However in a bad PDF as I have it in my collection
> (unfortunately I'm not allowed to disclose it) the object is an array
> (COSArray) which leads to the ClassCastException.
> Since the outline is an optional information the best we can do here is to
> ignore the 'outline' data if its not a COSDIctionary and return 'null'.
