> Currently, rehydrating a Pipeline works on the PCollection and PTransform levels with
the use of RawPTransform, but the runner-core-construction-java utilities will throw if the
runner attempts to deserialize a WindowingStrategy or Coder which contains non-Java custom
(or otherwise unknown) Coders or WindowFns.
>  
> Use a strategy like RawPTransform to deserialize WindowFns and Coders, so they can be
interacted with as intermediate tokens in the java form.
