TurfMeasurement#length method cannot handle empty lists

The other day, I encountered what I regard as an issue in the following Code snippet: https://github.com/mapbox/mapbox-java/blob/4ae8b78746fb37b2673364bdd4c8702057f3e7f3/services-turf/src/main/java/com/mapbox/turf/TurfMeasurement.java#L227
The scenario is the following: We have a list of GPS points of which some or all are invalid which is denoted by the coordinates being (0 , 0) - which IS bad Design, but our Team cannot change this... 🙄. Thus, we filter out those points before passing it to the length method. We just encountered an IndexOutOfBoundsException when the list is empty because there is no length check on the list. I guess the fix here is relatively easy, but the question ist - what should be returned in this case. We built in a check before hand returning 0 in this particular case. Maybe even a checked exception might be a feasible idea.

Commencez dans services-turf/src/main/java/com/mapbox/turf/TurfMeasurement.java, autour de la méthode length indiquée dans le lien, et reproduisez l’échec avec une liste vide. Vérifiez comment la méthode traite les listes normales de points et examinez les utilisations voisines afin d’établir le contrat prévu pour une entrée vide. Le travail est considéré comme terminé lorsque le comportement est convenu, que le cas d’une liste vide ne lève plus d’exception inattendue et que la couverture de régression le vérifie.
