>  with [[email protected]]. I start to analyze the usage of 
> {{ActorGatewayTaskExecutionStateListener}} and {{TaskExecutionStateListener}}.
> In conclusion, we abort {{TaskExecutionStateListener}} strategy and no any 
> component rely on it. Instead, we introduce {{TaskManagerActions}} to take 
> the role for the communication of {{Task}} with {{TaskManager}}. No one 
> except {{TaskManager}} should directly communicate with {{Task}}. So it can 
> be safely remove legacy class {{TaskExecutionStateListener}}.
