> Now `StaticInvoke` receives Any as a object and StaticInvoke can be serialized but sometimes the object passed is not serializable.
> For example, following code raises Exception because RowEncoder#extractorsFor invoked indirectly makes `StaticInvoke`.
> {code}
> case class TimestampContainer(timestamp: java.sql.Timestamp)
> val rdd = sc.parallelize(1 to 2).map(_ => TimestampContainer(System.currentTimeMillis))
> val df = rdd.toDF
> val ds = df.as[TimestampContainer]
> val rdd2 = ds.rdd                                 <----------------- invokes extractorsFor indirectory
> {code}
