I might have found a blocking issue [1]. The problem is that a StateDescriptor cannot be shared by multiple subtasks because they don't duplicate their serializer. As a consequence, things break if you have a stateful serializer. The problem exists since 1.0. However, given that this issue is really hard to debug for the user and one can easily fall into this trap, I would like to fix it for the release.
