You could think of adding a utility method on the RowTypeInfo:
```java
@SafeVarAgrs
RowTypeInfo.from(Class<?>... types)
```
and use it like
```java
StreamExecutionEnvironment.fromCollection(
rows,
RowTypeInfo.from(String.class, int.class));
```
> Cannot create Collection of Row

> Project: Flink
> Issue Type: Bug
> 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>
