      2019-07-31 06:47:31,919 ERROR [http-nio-8090-exec-3] [[Standalone].[localhost].[/].[file-server]] log Servlet.service() for servlet [file-server] in context with path [] threw exception

      • This error is NOT observed in version 6.6.13
      • Apparently this was fixed by CONFSERVER-31088. And this error is NOT observed in version 6.13.x and later.


      Either of follows.

      • Use .jpeg for the file extension instead of .jpg.
      • Upgrade to 6.7.2 or later which include the fix of CONFSERVER-31088
