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?

Thanks!
