Visible Anonymous Debugging Ontology

While beeing in debugging session, the Debugger creates an anonymous ontology. This anonymous ontology is a carbon copy of the active ontology and will be manipulated (adding, removing axioms) during the diagnosis search (reapairs).

The problem is that while beeing in a debugging session of one or more ontologies, the user can see these anonymous ontologies (he cannot debug then).

The fix for this bug is to use another OWLOntologyManager and not the same as it is used for the ontology to debug. This fix does also resolve Issue #87 (closed) .
