Andy Seaborne updated JENA-1354:
--------------------------------
Description:
Bug introduced by JENA-1329.
{noformat}
public static void main(String... args) {
Query q = QueryFactory.create("SELECT DISTINCT ?x {}") ;
Dataset ds = DatasetFactory.create();
//RDFDataMgr.loadDataset(dataFile) ;
QuerySolutionMap qsm = new QuerySolutionMap();
qsm.add("Z", ResourceFactory.createPlainLiteral("ZZZ"));
try(QueryExecution qExec = QueryExecutionFactory.create(q, ds, qsm)) {
qExec.execSelect().forEachRemaining(qs->System.out.println("qs=>
"+qs));
}
}
{noformat}
prints
{noformat}
qs=> ( ?Z = "ZZZ" )
{noformat}
when it should be
{noformat}
qs=>
{noformat}
This happens because of the DISTINCT makes the code not notice it is a root
iterator, not from a nested SELECT in a {{(sequence)}}.
