Thomas Groh resolved BEAM-1860.
-------------------------------
Resolution: Fixed
Fix Version/s: Not applicable
This is fixed as part of the broader push to get a meaningful Coder Hierarchy.
> SerializableCoder should not extend DeterministicStandardCoder

> Key: BEAM-1860
> URL: https://issues.apache.org/jira/browse/BEAM-1860
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-core
> Affects Versions: 0.6.0
> Reporter: Wesley Tanaka
> Assignee: Thomas Groh
> Fix For: Not applicable
>
>
> 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
