I think many shapes cut by the > MultipolygonRelation have this characteristic. the trick is that the merge is done for one sub division. That means that I just have to make sure that the number of points < 250 so that no further routine splits the shape. It might be possible to move the merge higher up in the chain, for example after the clipping. In that case I have to make sure that I don't create shapes that PolygonSubdivSizeSplitterFilter would split. I know that this is a bit risky, but maybe I can get rid of all Java2DConverter methods that convert to double and back to int.
