> Key: CALCITE-1436
> URL: https://issues.apache.org/jira/browse/CALCITE-1436
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Gian Merlino
> Assignee: Michael Mior
> Priority: Major
>
> AggregateNode.getAccumulator does this for any aggregation other than COUNT or SUM:
> final AggImpState agg = new AggImpState(0, call, false);
> int stateSize = agg.state.size();
> This NPEs because "state" is null on freshly created AggImpState instances.
