You are right. Done
> Simplify Row creation
> ---------------------
>
> Key: FLINK-5481
> URL: https://issues.apache.org/jira/browse/FLINK-5481
> Project: Flink
> Issue Type: Bug
> Components: DataSet API, Table API & SQL
> Affects Versions: 1.2.0
> Reporter: Anton Solovev
> Assignee: Anton Solovev
> Priority: Trivial
>
> When we use {{ExecutionEnvironment#fromElements(X... data)}} it takes first
> element of {{data}} to define a type. If first Row in collection has wrong
> number of fields (there are nulls) TypeExtractor returns not RowTypeInfo, but
> GenericType<Row>
