> The multiplication of two BigDecimal numbers sometimes returns null. Here is a minimal reproduction:
> {code:java}
> object Main extends App {
>   import org.apache.spark.{SparkConf, SparkContext}
>   import org.apache.spark.sql.SparkSession
>   import spark.implicits._
>   val conf = new SparkConf().setMaster("local[*]").setAppName("REPL").set("spark.ui.enabled", "false")
>   val spark = SparkSession.builder().config(conf).appName("REPL").getOrCreate()
>   implicit val sqlContext = spark.sqlContext
>   case class X2(a: BigDecimal, b: BigDecimal)
>   val ds = sqlContext.createDataset(List(X2(BigDecimal(-0.1267333984375), BigDecimal(-1000.1))))
>   val result = ds.select(ds("a") * ds("b")).collect.head
>   println(result) // [null]
> }
> {code}
