java.lang.IllegalArgumentException: An earlier entityClass (class org.optaplanner.examples.vehiclerouting.domain.Customer) should not be a subclass of a later entityClass (interface org.optaplanner.examples.vehiclerouting.domain.Standstill). Switch their declaration so superclasses are defined earlier.
