Elie Roux updated JENA-1380:
----------------------------
Description:
The Openllet reasoner introduces some owl:bottomObjectProperty triples that
seem to confuse Jena. I've opened an [openllet
ticket](https://github.com/Galigator/openllet/issues/17) about that. Here is
the code that makes Jena fail:
