I prefer ProcessInstances over Executions. Not only more understandable to the user, but consistent with the jBPM object model / API. In general I would try not to re-invent terms if jBPM already has a good term for something. ProcessDefinitions and ProcessInstances are not only jBPM terms, but are pretty much "industry standard" (as much as there are standards in the BPM market).
