Nick Dimiduk commented on FLINK-2124:
-------------------------------------
I'm also confused. Further debugging, and I tried out [~rmetzger]'s advice of
replacing fromElements with an anonymous instance of ParallelSourceFunction.
I'm still getting the same stack out of {{ClosureCleaner}} saying my object is
not serializable. Indeed, I do not implement {{Serializable}} for this object.
My understanding was that Flink handled conformant POJOs automatically. Is this
not the case with 0.9.1?
