Methods with this annotation will be called when a Processor or ReportingTask is no longer scheduled to run and all threads have returned from the onTrigger method. If such a method throws an Exception, a log message will be generated, and the Exception will otherwise be ignored; other methods with this annotation will still be invoked. Methods with this annotation are permitted to take either 0 or 1 argument. If an argument is used, it must be of type ConfigurationContext if the component is a ReportingTask or of type ProcessContext if the component is a Processor.
