> Calling {{JdbcTable.scan}} will result in a {{NullPointerException}} because
> inside {{JdbcTable.fieldClasses}} {{protoRowType}} is null.
> This could easily be fixed by replacing
> {code:java}
> final RelDataType rowType = requireNonNull(protoRowType,
> "protoRowType").apply(typeFactory);
> {code}
> with
> {code:java}
> final RelDataType rowType = getRowType(typeFactory);
> {code}
