> When creating the following user defined AGGREGATION and FUNCTION:
> {code:title=init.cql|borderStyle=solid}
> CREATE FUNCTION state_group_and_total(state map<uuid, int>, type uuid)
> RETURNS NULL ON NULL INPUT
> RETURNS map<uuid, int>
> LANGUAGE java AS '
> Integer count = (Integer) state.get(type);
> count = (count == null ? 1 : count + 1);
> state.put(type, count);
> return state;
> ';
> CREATE OR REPLACE AGGREGATE group_and_total(uuid)
> SFUNC state_group_and_total
> STYPE map<uuid, int>
> INITCOND {};
> {code}
> And creating a statement like:
> {code}
> SELECT group_and_total("id") FROM mytable;
> {code}
> When mytable is empty, it throws the following null assertion
> {code}
