Do you have a sample pdf, or why do you ask?

> We are trying to detect files which contain several objects with the same identifier within a revision or in a given PDF. Currently, that seems not possible. We are facing to this [map|https://github.com/apache/pdfbox/blob/2.0.21/pdfbox/src/main/java/org/apache/pdfbox/cos/COSDocument.java#L56] which only allows one instance by object id. The map usage brings limitations (eg : rendering,...).
> Is that possible to detect such files ?
