Review comment:
Please add tests for table API as well. I would expect there to have this
error:
```
org.apache.flink.table.api.ValidationException: Cannot translate a query
with an unbounded table function call.
at org.apache.flink.table.api.Table.getRelNode(table.scala:94)
at
org.apache.flink.table.utils.StreamTableTestUtil.printTable(TableTestBase.scala:321)
```
