This indeed was the problem. Point is; I simply used code completion on the Change class, found the getRemoved method, and used that. I figure this will be happening to a lot of people. Maybe it is user friendly to provide a small hint in the IllegalStateException's text, something like "Have you maybe forgotten to iterate over the change sets?".
