Operation's paths specified via inherited base class are not honored

[trurli]

Given a controller implementation that inherits from a base class, e.g. ControllerImpl extending BaseController and a @RequestMapping("/base") at the class-level on BaseController and an annotation @RequestMapping("/operation") on some operation in ControllerImpl, the resulting generated OpenAPI spec will just list /operation as its path, although in reality the operation is reachable via /base/operation.
