> The function "avg_state" is created with a non-frozen tuple argument {{state}} and return
type. It should be non-frozen because it's modified by the code in the body of the UDF.
> {code}
> CREATE KEYSPACE examples WITH replication = { 
>   'class': 'SimpleStrategy', 'replication_factor': '3' };
> CREATE FUNCTION examples.avg_state(state tuple<int, bigint>, val int)
>   CALLED ON NULL INPUT RETURNS tuple<int, bigint>
>   LANGUAGE java AS
>   'if (val != null) {
>     state.setInt(0, state.getInt(0) + 1);
>     state.setLong(1, state.getLong(1) + val.intValue());
>   }
> return state;'
> {code}
> However, the schema metadata has the both the {{state}} argument and the return type
incorrectly defined as {{frozen<>}}:
> {code}
> cqlsh> SELECT argument_types, return_type FROM system_schema.functions WHERE keyspace_name
= 'examples' AND function_name = 'avg_state';
>  argument_types                        | return_type
> ---------------------------------------+----------------------------
>  ['frozen<tuple<int, bigint>>', 'int'] | frozen<tuple<int, bigint>>
> {code}
