Problem with rdfs:subClassOf* and TDB (Jena 2.10)

[Christian Jauvin]

Hi,

I'm using TDB (Jena 2.10) and this simple SPARQL query (run with
"tdbquery") over a store of ~1000 triples (which is actually a dump of
an OWL ontology):

select (count(?x) as ?cnt)
where { ?x rdfs:subClassOf* ?y }

gives the error:

11:03:03 ERROR TDB                  ::
ObjectFileStorage.read[nodes.dat](16221)[filesize=49330][file.size()=49330]:
Impossibly large object : 825189752 bytes >
filesize-(loc+SizeOfInt)=33105
com.hp.hpl.jena.tdb.base.file.FileException:

whereas the same query, over the same ontology in Protege runs fine
(and yields a count of 3062, proving that this is not an "impossibly
large object").

Note that the same query, with the non-transitive version of the operator:

select (count(?x) as ?cnt)
where { ?x rdfs:subClassOf ?y }

runs fine in TDB (and yields 170).

Thanks,

Christian
