> Use StaticInvoke rather than NewInstance for boxing primitive types
> -------------------------------------------------------------------
>
> Key: SPARK-20289
> URL: https://issues.apache.org/jira/browse/SPARK-20289
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Reynold Xin
> Assignee: Reynold Xin
>
> Dataset typed API currently uses NewInstance to box primitive types (i.e.
> calling the constructor). Instead, it'd be slightly more idiomatic in Java to
> use PrimitiveType.valueOf, which can be invoked using StaticInvoke expression.
