> The runtime (`StreamTwoInputSelectableProcessor#checkFinished()`) switches
> the input selection when one input is finished, because
> `BoundedxInput.endInput()` was not supported before the PR#8731
> (https://github.com/apache/flink/pull/8731) is merged. Now we should change
> the logic of `StreamTwoInputSelectableProcessor#checkFinished()` to invoke
> `InputSelectable#nextSelection()`, and the input selection should been
> switched in `endInput()` by the operator.
