[owl-s] Duplicate service objects?

[Jim Andreou]

Apparently, this is caused by this (OWLKnowledgeBaseImpl.java), see inline
comments:
public List<Service> getServices()
{
final OWLIndividualList<OWLIndividual> inds =
OWLFactory.createIndividualList();
inds.addAll(getInstances(OWLS.Service.Service)); // <--- this line must be
deleted
for (final OWLClass serviceClass : getSubClasses(OWLS.Service.Service,
false))
{
                        //because serviceClass also becomes
OWLS.Service.Service
inds.addAll(getInstances(serviceClass));
}
return OWLFactory.wrapList(inds, Service.class);
}
