I am doing something a bit odd. There is one imported model that gets reloaded from time-to-time, at the end of which I do an ontModel.getBaseModel().rebind(). (The overall intent is sort of a backwards base v schema workflow, where it is a small set of definitions and axioms applied to the same big base model that get changed.) I get this exception shortly after doing a reload/rebind, such as the first one or few queries (as in this stackdump). After that things seem to work OK. I only get the one exception after a reload/rebind. I'd still like to (someday) understand what I'm doing, though.
Openllet/Pellet doesn't do this, but that is overkill and noticeably slower for many workflows.
There is some punning done in the big base model, but works OK in many workflows. This is the only case where I have seen anything other than a few "not supported" warnings.
