Amir Hooshmand commented on JENA-1938:
--------------------------------------
Thanks for the comment, but of-course it is a bug, please see below from Jena
Documentation:
* "The Jena Ontology API is language-neutral: the Java class names are not
specific to the underlying language. For example, *the {{OntClass}} Java class
can represent an* *OWL class or RDFS class*. To represent the differences
between the various representations, each of the ontology languages has a
_profile_, which lists the permitted constructs and the names of the classes
and properties."
* Check here: [https://jena.apache.org/documentation/ontology/]
> 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 best knowledge);
> * ontClass.listNamedClasses();
> * ontClass.listClasses();
> The Bug is in "org.apache.jena.ontology.impl" in
> * OWLProfile Class,
> * method getClassDescriptionTypes()
> * in Line 218
> My suggestion to fix the bug:
> * add <<< RDFS.Class >>> to the ArrayList.
>
> Thanks
