> Currently for event-time window(group/over), When contain `Timestamp` type
> field in `SELECT Clause`, And toDataStream[T], `T` not a `Row` Type, Such
> `PojoType`, will throw a exception. In this JIRA. will fix this bug. For
> example:
> Group Window on SQL:
> {code}
> SELECT name, max(num) as myMax, TUMBLE_START(rowtime, INTERVAL '5' SECOND) as
> winStart,TUMBLE_END(rowtime, INTERVAL '5' SECOND) as winEnd FROM T1 GROUP BY
> name, TUMBLE(rowtime, INTERVAL '5' SECOND)
> {code}
> Throw Exception:

> In fact, when we solve this exception,subsequent other exceptions will be
> thrown. The real reason is {{TableEnvironment#generateRowConverterFunction}}
> method bug. So in this JIRA. will fix it.
