Getting 500 when Accessing /testFiles page

[jasonarcala]

From the documentation, it stated that users are able to upload test files similar to the schematron page. I'm getting the error below when navigating to /testFiles page.

Are you installing this on your own server? If using a Linux box, make sure all of the data directories have full permissions for tomcat user. Also, on those machines, double-check the case of all directory names.
Does this error happen with any file, or only under test files? Does it happen with only one specific test file, or all test files?

I'm actually trying to get this running inside a tomcat docker container. I'll create a pull request so it can be easily reproducible.
