Hi all,
Has anyone seen something like the stacktrace listed below before? I'm
trying to generate provenance rdf in a service running in an Karaf OSGi
runtime, but when it gets to:
final OntModel model =
ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
It has trouble creating the OntModel object because of the stack trace
below. I'm guessing it has to do with the classes available to it at
runtime, as it runs fine outside of the OSGi container.
