SPARQL query doesn't update the ontology

Hello, I was using the codes from example 8) in Wiki, but it seems that the ontology I got still has AnnotationProperty in it, and the ObjectProperty did not replace them. I used ontapi 3.0.4, owlapi-distribution 5.5.0, apache-jena 4.5.0 and jena-arq 4.5.0. The output I got is as follows:

Declaration(AnnotationProperty(<http://ex.com/test#prop1>))
Declaration(AnnotationProperty(<http://ex.com/test#prop2>))
Declaration(Class(<http://ex.com/test#class1>))
ClassAssertion(<http://ex.com/test#class1> <http://ex.com/test#indi1>)
AnnotationAssertion(<http://ex.com/test#prop1> _:7c02ddfe-45c2-48ee-8e23-558b6b2032d8 <http://ex.com/test#indi1>)
SubAnnotationPropertyOf(<http://ex.com/test#prop2> <http://ex.com/test#prop1>)
AnnotationPropertyDomain(<http://ex.com/test#prop1> <http://ex.com/test#class1>)
@prefix owl:  <http://www.w3.org/2002/07/owl#> .
@prefix rdf:  <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix xsd:  <http://www.w3.org/2001/XMLSchema#> .

<http://ex.com/test#prop1>
        rdf:type     owl:AnnotationProperty ;
        rdfs:domain  <http://ex.com/test#class1> .

<http://ex.com/test#prop2>
        rdf:type            owl:AnnotationProperty ;
        rdfs:subPropertyOf  <http://ex.com/test#prop1> .

[ <http://ex.com/test#prop1>  <http://ex.com/test#indi1> ] .

<http://ex.com/test>  rdf:type  owl:Ontology .

<http://ex.com/test#class1>
        rdf:type  owl:Class .

<http://ex.com/test#indi1>
        rdf:type  <http://ex.com/test#class1> , owl:NamedIndividual .

I merely changed anything in the example except OWLDataFactory df = m.getOWLDataFactory(); as DataFactory df = m.getOWLDataFactory();. The classes I imported are:

import org.apache.jena.query.QueryExecution;
import org.apache.jena.query.QueryExecutionFactory;
import org.apache.jena.query.QueryFactory;
import org.apache.jena.query.ResultSet;
import org.apache.jena.update.UpdateAction;
import org.semanticweb.owlapi.model.IRI;
import org.semanticweb.owlapi.model.OWLAnnotationProperty;
import org.semanticweb.owlapi.model.OWLClass;
import org.semanticweb.owlapi.model.OWLNamedIndividual;
import org.semanticweb.owlapi.model.OWLOntologyStorageException;

import com.github.owlcs.ontapi.DataFactory;
import com.github.owlcs.ontapi.OntManagers;
import com.github.owlcs.ontapi.Ontology;
import com.github.owlcs.ontapi.OntologyManager;

I also tried to remove the parts for updating / printing declaration and got a slightly different output. Removing updating or printing declaration printed [ <http://ex.com/test#prop1> <http://ex.com/test#indi1> ] . at the end of the output. Removing both printed [ <http://ex.com/test#prop1> <http://ex.com/test#indi1> ] . between prop1 and prop2.

Update: I used my local OWL ontology file, and it worked. Possibly, the issue is relevant to creat a new ontology, but I haven't tested that part.
