Review comment:
@apilloud
My understanding now is if a `Object[]` contains one single element, that
single element has to be added to queue (not Object[]). That's why NPE happens.
If not do so, some driver tests will break due to Calcite implementation.
I don't think there will be a `null` for `Object[]`.
