Description

I get the below exceptions when calling pdfDoc.getDocumentCatalog().getAllPages(). The code continues after the first exception because I've called PDDocument.load("C:/CancerSummReport_34914.pdf", true) setting the load "force" param to true. The second exception causes the code to abort.

(I will try uploading the PDF that causes this problem)
