      Issue Summary

      In Confluence 7.12 and above, accessing the Files and images dialog to upload an image file will result in java.lang.NullPointerException in the <Confluence-Home>/logs/atlassian-confluence.log file.

      Steps to Reproduce

      1. Create a new page in Confluence or edit an existing Confluence page.
      2. Load up the Files and images dialog.
      3. Upload an image file (of any image file extension) to the page.

      The same java.lang.NullPointerException would also be thrown in the <Confluence-Home>/logs/atlassian-confluence.log when accessing the Files and images dialog of a page with an attachment image already embedded into it.

      Expected Results

      The page and its embedded attachments are load up fine without any errors thrown in the <Confluence-Home>/logs/atlassian-confluence.log.

      Actual Results

      The page and its embedded attachments are load up fine, but the below exception is thrown in the <Confluence-Home>/logs/atlassian-confluence.log file:

      2021-05-26 14:06:42,229 ERROR [http-nio-27120-exec-5] [[Standalone].[localhost].[/c7120].[file-server]] log Servlet.service() for servlet [file-server] in context with path [/c7120] threw exception

            Just got this on 7.18.2

             ERROR [http-nio-8090-exec-12] [[Standalone].[localhost].[/].[file-server]] log Servlet.service() for servlet [file-server] in context with path [] threw exception
java.lang.NullPointerException

            @Jiri any idea why this would return and how to counter it?
