    [ https://issues.apache.org/jira/browse/PDFBOX-5539?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17681764#comment-17681764 ] 

Andreas Lehmkühler commented on PDFBOX-5539:
--------------------------------------------

How about adding {{org.apache.pdfbox.cos.COSDocument.xrefTable}} somewhere in the debugger?

> For analyzing potentially erroneous PDFs it would be quite helpful to be able to show the CRT (Cross Reference Table/xref) and navigate to its entries.
> Some software does provide rather technical (and therefore quite precise) information about errors in the PDF files mentioning the object number in the pdf file instead of page numbers. With PDF-Debugger, I currently have to navigate the Document Catalog Tree structure to find the object. Furthermore, navigating the tree structure does enable one to view unreferenced objects.
