> {{AbstractInvokable.restore}}, however, if
> [invokable.restore()|https://github.com/apache/flink/blob/79a521e08df550d96f97bb6915191d8496bb29ea/flink-runtime/src/main/java/org/apache/flink/runtime/taskmanager/Task.java#L754-L759]
> throws exception out, no more {{StreamTask#cleanUpInvoke}} would be called,
