I get:

org.semanticweb.owlapi.model.OWLOntologyRenameException: Could not
rename ontology. An ontology with this ID already exists:
<http://www.ontologydesignpatterns.org/cp/owl/collectionentity.owl>

and that's because you're trying to load the second ontology, which
was already imported. Use getOntology instead of loadOntology and it
will work.
HTH,
