问题产生的条件：
方法的返回值为基本数据类型,且拦截器的beforeInvoke返回false

发生问题的调用代码：
public class SecurityMethod {
    @Aop(value={"check"}) 
    public int giveMeMoney(){
        return Integer.MAX_VALUE;
    }
}

//ioc容器中的名字为"check"
public class Check extends AbstractMethodInterceptor {

public boolean beforeInvoke(Object obj, Method method, Object... args) {
    return false;
}
}
异常堆栈:
Exception in thread "main" java.lang.NullPointerException
    at org.nutz.aop.demo.target.SecurityMethod$$NUTZAOP.giveMeMoney(Unknown
Source)
    at org.nutz.aop.demo.DemoA.main(DemoA.java:32)

字节码没有处理 WrapperClass 吧，呵呵 ^_^

错, 处理了.只是没有考虑到一个情况:
Integer it = null;
it.intValue();
这样会爆NPE

被拦截的是原生类型返回值，也会得到 null ?
