      Problem

      View PDF Macro does not render some PDF files.

      This could be replicated using some exported PDFs from Google Chrome, like from atlassian.com
      This could affect other PDFs too.

      Environment

      Tested this on Confluence DC 7.19.14 , 8.3.2, 8.4.2 and 8.5

      Steps to Reproduce

      • Access a web page using Google Chrome.
      • Select File > Print > Save the page as PDF.
      • Add this PDF as an attachment to a page.
      • Use the PDF view macro and select the PDF you attached.
      • Publish the page.

      No exception is seen on logs by default, but if sandbox debug is enabled we can see the below java.lang.NullPointerException:

      Expected Results

      The PDF renders fine.

      Actual Results

      PDF preview is garbled and unreadable.

      Workaround

      Solution 1:

      • Export the PDF again using another application 

      Solution 2:

      • Open the PDF in another software like Adobe Reader or Safari.
      • Print the file as a PDF again.

      Using "Save as" will not fix the PDF.

      Solution 3: 

      • Although it has fewer features it is possible to preview the PDF using the View File macro.
