> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> 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).
