> The FingerprintFactory will create Processor objects and invoke their initialize() and
@OnAdded methods.  If a Processor uses system resources, these methods are where those resources
are allocated.  But, those processors are never disposed by calling their @OnRemoved or @OnShutdown
methods.  This may result in system resource leaks, depending on how processors are implemented.
> To reproduce, add a processor to the NiFi graph and restart NiFi.  Note that initialize()
and @OnAdded is called at least twice (I observed 3 times) as NiFi starts.  The getIdentifier()
is different for each invocation.  Shutdown NiFi and observe that @OnShutdown is called once.
