Hello, I've been playing with UDFs using the Scala API and have repeatedly run into issues such as this: ``` flink-taskmanager_1 | java.lang.ClassCastException: scala.collection.immutable.Set$EmptySet$ cannot be cast to [J ``` Is there something that can be done on Flink's end, either to catch these errors in type checking or to cast them in a sane manner during runtime?
