>             Project: Apache Jena
>          Issue Type: Bug
>    Affects Versions: Jena 3.2.0
>            Reporter: Andy Seaborne
>            Assignee: Andy Seaborne

> Example:
> {noformat}
> public class CheckQueryIterator {
>     public static void main(String... args) {
>         String queryStr = "SELECT ?s { } GROUP BY ?s";
>         Query query = QueryFactory.create(queryStr);
>         Model model = ModelFactory.createDefaultModel();
>         try(QueryExecution qe = QueryExecutionFactory.create(query, model)) {
>             ResultSet rs = qe.execSelect();
>             // Do not "hasNext"
>             //rs.hasNext();
>         }
>     }
> {noformat}
> Key feature: not touching the "group", going straight to {{QueryExecution.close()}}.
> This does not cause any incorrect query results.
