It's still valid, I think the names are still off
```
public abstract class StreamTask<OUT, O extends StreamOperator<OUT>>
extends AbstractInvokable implements
OperatorStateCarrier<StateHandle<Serializable>>,
CheckpointedOperator, CheckpointNotificationOperator {
```
The StreamTask implements interfaces that have Operator in their names, and
they are inconsistent.
