Yes that sounds right, the level should be set to SEVERE

> In class MultiPolygonRelation we have quite a lot of methods which is meant to be skipped if logging is not enabled but because of this bug(?) the code is executed sometimes, maybe with side effects that I don't yet fully understand.

There shouldn't be any extra side effects, but it may be a little quicker.
