I can't reproduce this with a dummy example just containing a single OWL
class with a single individual.
Both ways return the individual. Do you have some inference enabled?
Can you share sample data and code? All entities are strongly typed
(don't know if this matters here)?
OntModel::listIndividuals(type) calls
getGraph().find( null, RDF.type.asNode(), type.asNode() );
OntClass::listInstances() does
getModel()
.listStatements( null, RDF.type, this )
.mapWith( s -> s.getSubject().as( Individual.class ) )
.filterKeep( o -> o.hasRDFType( OntClassImpl.this,
direct ))
.filterKeep( new UniqueFilter<Individual>());

Given an OntModel myModel and an OntClass myClass contained in
myModel, the call myModel.listIndividuals(myClass) provides the
expected list of Individuals that are members of myClass; but the call
myClass.listInstances() doesn't list anything. I am curious what the
difference is between the two (I was not able to make that out from
the javadoc).
