> Not sure if this is just a doc bug, but:
> https://beam.apache.org/documentation/sdks/javadoc/0.6.0/org/apache/beam/sdk/coders/SerializableCoder.html says:
> SerializableCoder does not guarantee a deterministic encoding, as Java serialization may produce different binary encodings for two equivalent objects.
> Yet https://beam.apache.org/documentation/sdks/javadoc/0.6.0/org/apache/beam/sdk/coders/DeterministicStandardCoder.html says:
> A DeterministicStandardCoder is a StandardCoder that is deterministic, in the sense that for objects considered equal according to Object.equals(Object), the encoded bytes are also equal.
> These sound like they conflict, and thus that SerializableCoder should not extend DeterministicStandardCoder
