Мы используем OptaWeb Vehicle Routing и создаем автомобили и локации. Иногда мы получаем следующую ошибку:
The workingObjects (PlanningVehicle{capacity=20,depot=1,id=9}, PlanningVehicle{capacity=20,depot=1,id=9}) have the same planningId ((class org.optaweb.vehiclerouting.plugin.planner.domain.PlanningVehicle,9)). Working objects must be unique.
След стека выглядит следующим образом:

Кажется, что это случайно, и мы не можем найти решение. Любые идеи? Спасибо!
