@OnUnscheduled
Methods with this annotation will be called whenever a Processor or ReportingTask is
no longer scheduled to run. At that time, many threads may still be active in the
Processor's onTrigger
method. If such a method throws an
Exception, a log message will be generated, and the Exception will be otherwise ignored
and other methods with this annotation will still be invoked. Methods with this
annotation may take zero arguments or may take a single argument. If the single argument
variation is used, the argument must be of type ProcessContext
if the
component is a Processor or ConfigurationContext
if the component is
a ReportingTask.
