Description
When a plugin attempts to send an email notification (when a smart commit fails, say), with certain email configurations, the following exception is thrown when the email notification is processed by FishEye:

This is happening because we are adding a Notification object to a TreeSet. The contract for a TreeSet is:
All elements inserted into the set must implement the Comparable interface.
