* Interface mixed into Throwables thrown from Spark.
*
* - For backwards compatibility, existing Throwable types can be thrown with an arbitrary error
* message with a null error class. See [[SparkException]].
* - To promote standardization, Throwables should be thrown with an error class and message
* parameters to construct an error message with SparkThrowableHelper.getMessage(). New Throwable
* types should not accept arbitrary error messages. See [[SparkArithmeticException]].
*
* @since 3.2.0
