I'm on fedora 25 and using all the built-in or from repo dependencies for
guacamole. Unfortunately the application fails to start within tomcat. The
only logs I have so far are:

If you need anymore logs or information please let me know how to enable the
debugging required in tomcat. The only thing I can note is there is no
default properties file in /etc/guacamole on fedora 25, only a
user-mapping.xml file..
