10 years ago Reloading an ontology does not reset the named entries on all named entities when cleaning. As a result, the name collections are cleared but not refilled, and this causes individuals to not be found.
Fix is to reset the named entries on all the entities in the ontology signature.
@Test public void shouldLoadAndNotFailQuery() throws Exception { // given OWLOntology o = OWLManager.createOWLOntologyManager().createOntology(); OWLOntologyManager m = o.getOWLOntologyManager(); OWLDataFactory f = m.getOWLDataFactory(); OWLClass c1 = f.getOWLClass(IRI.create("urn:test#c1")); OWLClass c2 = f.getOWLClass(IRI.create("urn:test#c2")); OWLObjectProperty p = f.getOWLObjectProperty(IRI.create("urn:test#p")); m.addAxiom(o, f.getOWLDisjointClassesAxiom(c1, c2)); m.addAxiom(o, f.getOWLObjectPropertyDomainAxiom(p, c1)); m.addAxiom(o, f.getOWLObjectPropertyRangeAxiom(p, c2)); OWLReasoner r = new JFactFactory().createReasoner(o); r.precomputeInferences(InferenceType.CLASS_HIERARCHY); OWLIndividual i = f.getOWLNamedIndividual(IRI.create("urn:test#i")); OWLIndividual j = f.getOWLNamedIndividual(IRI.create("urn:test#j")); m.addAxiom(o, f.getOWLObjectPropertyAssertionAxiom(p, i, j)); r.flush(); r.precomputeInferences(InferenceType.CLASS_HIERARCHY); OWLIndividual k = f.getOWLNamedIndividual(IRI.create("urn:test#k")); OWLIndividual l = f.getOWLNamedIndividual(IRI.create("urn:test#l")); m.addAxiom(o, f.getOWLObjectPropertyAssertionAxiom(p, k, l)); r.flush(); r.precomputeInferences(InferenceType.CLASS_HIERARCHY); }
