The code tested is the following:

OWLOntologyManager manager = OntManagers.createONT();   
OWLDataFactory factory = manager.getOWLDataFactory();
OWLOntology ontology=manager.loadOntologyFromOntologyDocument(
        new File("ontologies/E1G1.owl"));

My pom file contains the following dependencies:ontapi1 .1.0, jena-arq 3.6.0, openllet-pellint 2.6.3.


Solution

  • Ensure you only have one owlapi version in the claaspath. The stack trace implies there are at least two versions.
