StateSpec from hashCode of SimpleStateTag
URL: https://github.com/apache/beam/pull/8555#issuecomment-491902361
@lukecwik sorry I didn't respond, is the issue you mentioned related to
this? It seems to me, that it refers to storing user supplied keys in user
states (which currently behaves similarily to how java collections work, which
might not be an issue), or am I missing something?

> SimpleStateTag is used as key in hash based StateTable, and currently is
> hashes and compares StateSpec and StructuredId, that are inside the
> SimpleStateTag. StateSpec hashes Coder into the resulting hashCode and when
> the Coder fails to have a proper hashCode and equals implementations, it
> results in wrong behavior (apparently missing states).
