What would the following exception be caused by?
Dataset dataset = TDBFactory.createDataset(directory);
dataset.begin(ReadWrite.WRITE);
Model m =dataset.getNamedModel("metadata");
OntModel model =
ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM_RULE_INF,
m);
for (Iterator<Individual> indIter = model.listIndividuals(); indIter
.hasNext();) {
Individual ind = indIter.next();
System.out.println("INX: " + ind.getLocalName());
}

This is in a step where I am simply trying to list the individuals within an
ontology after I retrieve it from TDB. I've created two individuals, linked
them with ObjectProperties, and wrote the TDB store. Neither of the statements
has anything to do with dateTime. The statements do appear when I call
listStatements(), and the ontology is valid and clean.
Any suggestions where to look for what causes this would be appreciated.
