      Description

      When you have a key/value class that's non Writable and you forget to attach io.serializers for the same, an NPE is thrown by the tasks with no information on why or what's missing and what led to it. I think a better exception can be thrown by SerializationFactory instead of an NPE when a class is not found accepted by any of the loaded ones.
