Yup, this problem happened since the very first time I ran it on an empty database. The terms get created in term, the term representing the triple gets created in term, but it does not create the relationship in term_relationship.
The exception is being thrown by the persistTerm call on the very first line of persistTriple. I'm thinking that this is something to do with the OntologyMonitor? That it is seeing the Triple get created, but because the Triple is an instanceof Term it is firing two change events - one for the Term representation, the other for the Triple representation? That's the only way I can see the Triple being created in the term table but not in the term_relationship table, as otherwise we'd be getting exceptions halfway through persistTriple way after that call to persistTerm at the beginning, which we're not. In other words, the Triple already exists in the term table _before_ persistTriple is getting called. Why? How?
