为什么cglib动态代理执行顺序随机？

不像JDK代理一样打印，代理前->执行代理对象->代理后；
而是代理对象执行随机好像。

class People{
    void hello(String arg) {
        System.out.println(arg);
    }
}
public class CglibProxy implements MethodInterceptor {

    public Object getProxy(Class cls) {
        Enhancer enhancer = new Enhancer();
        enhancer.setSuperclass(cls);
        enhancer.setCallback(this);
        return enhancer.create();
    }

    /***

     * 为什么这个动态代理奇怪在它的打印顺序是随机的。不保序；
     */
    @Override
    public Object intercept(Object proxy, Method method, Object[] args, MethodProxy methodProxy) throws Throwable {
        System.err.println("say it for always");
        Object result = methodProxy.invokeSuper(proxy, args);
        System.err.println("say it together");
        return result;
    }


    public static void main(String[] args) {
        CglibProxy cp = new CglibProxy();
        People obj = (People)cp.getProxy(People.class);
        obj.hello("And what they played was a masquerade");
    }
}
