      Notes

      This does not affect Confluence Server in Windows nor Confluence Data Center on Linux.
      This is a regression of bug CONFSERVER-24389 – Export to PDF on Windows returns a stack trace if the name of the page has a ':' symbol.

      Workaround

      There are two options to circumvent this problem:

      1. Advise users to remove the ':' character from pages' title.
      2. Disable PDF exports to be handled by the sandbox process by adding the following JVM argument and restart Confluence: 
        -Dpdf.export.sandbox.disable=true
