> {{SchedulingStrategy}} requires task states to make scheduling decisions.
> At the moment, however, only FINISHED and FAILED states are notified. 
> According to {{SchedulingStrategy#onExecutionStateChange}} definition, all task state changes should be notified to {{SchedulingStrategy}}, including those from TMs and from within JM.
> This can be helpful for a more flexible scheduling.
