Actual results:
Non-superuser sees no Tomcat AutoGroup metric graphs and strange exception when attempting to view metric tables.

Expected results:
Metric graphs and metric tables as non-superuser

Additional info:
This issue may not be limited to the AutoGroup displays of a Tomcat server and may not occur if other role permissions are used.  The testing was limited to this specific use-case.
