Hi, i have a problem with generating appropriate constraints with the following class structure.
Image


when hibernate generates the ddl for this structure. it adds a constraint into Drivers for Car, Bike and Truck. but it only needs a constraint into Vehicle since Car Bike and Truck use PFK for vehicle_id.

How can i annote the one to many association with MotorVehicle and Drivers appropriately so that this is captured by jpa?
