Using SPARQL to get the first entity of superclasses of a certain class

Question

I use Jena from Java code and Blazegraph as a server, I have tried to query the first superclass in a path of a certain class, and of course, I didn't use either * or + with the predicate rdfs:subClassOf.

The query works well from the Blazegraph interface, but when I try to apply the query from Jena and Java, it returns all superclasses!

The followings are the query and the code:

PREFIX snomed-ct: <http://ihtsdo.org/snomedct/clinicalFinding#> 
SELECT DISTINCT * 
WHERE { 

  snomed-ct:47686007 rdfs:subClassOf  ?Identifier. 
}

Query query = QueryFactory.create(queryString); 
QueryExecution qExe = QueryExecutionFactory.sparqlService("http://localhost:9999/blazegraph/namespace/snomed/sparql", query);
ResultSet results = qExe.execSelect();

I noted this, when I use the web interface of Blazegraph with URL "localhost" the query work well, but if I put the IP address instead of localhost the query returns all superclasses, but from Java code neither change using localhost or IP.
