[jira] [Created] (JENA-1938) OntClass query does not return classes that are of type RDFS.Class

Amir Hooshmand created JENA-1938:
------------------------------------

             Summary: OntClass query does not return classes that are of type RDFS.Class
                 Key: JENA-1938
                 URL: https://issues.apache.org/jira/browse/JENA-1938
             Project: Apache Jena
          Issue Type: Bug
          Components: Ontology API
    Affects Versions: Jena 3.16.0
         Environment: Team,

There is a bug in the Ontology API; the OntClass query does not return classes that are RDFS.Class. You receive only OWL.Class and OWL.Restriction classes

There are two functions affected due to this bug (to my knowledge);
 * ontClass.listNamedClasses();
 * ontClass.listClasses();

The Bug is in "org.apache.jena.ontology.impl" in
 * OWLProfile Class,
 * method getClassDescriptionTypes()
 * in Line 218

To fix the bug, we need to add <<<<<< RDFS.Class >>>>> to the ArrayList. 

Thanks

AHOO
