      This is caused by a bug in the PDFBOX stated here: https://issues.apache.org/jira/browse/PDFBOX-1756

      Confluence 5.7.3, 5.8.2 and 5.8.4 ships the version 1.8.4 of pdfbox, which is affected by the bug.

      Workaround

      1) Disable the indexing of PDF attachments using this guide
      OR
      2) Update the pdfbox plugin manually in Confluence_install\confluence\WEB-INF\lib folder by replacing the original pdf plugin with a version 1.8.6 or newer. Download the newer version here
