------------------------------------
[~kezhuw] I think that the `disposeAllOperators` should use asynchronous calls
and set timeouts just like the cancel task, just as the line 'Task
cancelOrFailAndCancelInvokable' 1065

> When a StreamTask exits due to an internal exception, the StreamTask does not
> use an asynchronous thread to closeAllOperators or set a timeout. The
> StreamTask will be stuck here (no upstream and downstream scenarios)
