> Users of the Table API in Java will get several warnings about the usage of Rows even though the table program is specified correctly.
> {code}
> org.apache.flink.api.java.typeutils.TypeExtractor - class org.apache.flink.types.Row is not a valid POJO type
> {code}
> We should improve the user experience here. A correctly defined table program should not cause those messages. Users of the row type should rather be informed that they have to provide type information manually.
