> Using {{ResultSetClosable}} leads to a NPE for {{QueryExecution}} objects that have been created based on the query string only, i.e. without a parsed {{Query}} object because of the [sanity check|https://github.com/apache/jena/blob/master/jena-arq/src/main/java/org/apache/jena/query/ResultSetCloseable.java#L38] regarding {{SELECT}} queries. 
> Example:
> {code:java}
> QueryEngineHttp qe = new QueryEngineHttp("http://dbpedia.org/sparql", "select * { ?s ?p ?o } limit 1");
> try(ResultSetCloseable rs = ResultSetCloseable.closableResultSet(qe)) {
>   rs.hasNext();
> }
> {code}
