Runtime error when using a List in a case class

[erwan]

I'm trying to use List in my model, however when I do that I have runtime exception during my tests. It seems like I end up with a broken model, with a List that throws whatever I do with it. I'm getting a java.util.NoSuchElementException: head of empty list exception from inside the Scala standard lib, so it's neither empty nor containing valid values.

I created a repro as a new test in this branch: https://github.com/erwan/flink-adt/tree/list-minicluster

Is there anything I should do differently here? Or maybe that would be a bug in flink-adt?
