@Override
public Processor createProcessor(RouteContext routeContext) throws Exception {
    Policy policy = resolvePolicy(routeContext);
    ObjectHelper.notNull(policy, "policy", this);
    // before wrap
    policy.beforeWrap(routeContext, this);
    // create processor after the before wrap
    Processor childProcessor = this.createChildProcessor(routeContext, true);
    // wrap
    Processor target = policy.wrap(routeContext, childProcessor);
    if (!(target instanceof Service)) {
        // wrap the target so it becomes a service and we can manage its lifecycle
