Я пытаюсь сгенерировать онтологию с помощью OWL API в Eclipse neon. В нем нет ошибок, но не удалось выполнить.

 public class TestOntology {
    public static void main(String[] args) {    
OWLOntologyManager man = OWLManager.createOWLOntologyManager();
        IRI ontologyIRI = IRI.create("http://130.88.198.11/co-ode-files/ontologies/pizza.owl");
        try {
        OWLOntology ontology = man.loadOntology(ontologyIRI);
        System.out.println(ontology.getLogicalAxiomCount());
        } catch (OWLOntologyCreationException e) {
        e.printStackTrace();
        }

*my error*

версия класса 51 — Java 7. Используете ли вы OWLAPI 4 на Java 6?

Минимальным требованием для OWLAPI 4 является Java 7.
