JVM打破双亲机制出现异常

添加loadClass方法后会出现D:\test\java\lang\Object.class (系统找不到指定的路径。)，不添加该方法就可以找到，不会出现异常，user1中有个sout方法

package com.tuling.jvm;

import java.io.FileInputStream;
import java.lang.reflect.Method;
import java.lang.ClassLoader;


public class MyClassLoaderTest {
    static class MyClassLoader extends ClassLoader {
        private String classPath;

        public MyClassLoader(String classPath) {
            this.classPath = classPath;
        }

        private byte[] loadByte(String name) throws Exception {
            name = name.replaceAll("\\.", "/");
            FileInputStream fis = new FileInputStream(classPath + "/" + name + ".class");
            int len = fis.available();
            byte[] data = new byte[len];
            fis.read(data);
            fis.close();
            return data;
        }

        @Override
        protected Class<?> findClass(String name) throws ClassNotFoundException {
            try {
                byte[] data = loadByte(name);
                //defineClass将一个字节数组转为Class 对象，这个字节数组是class 文件读取后最终的字节数组。
                return defineClass(name, data, 0, data.length);
            } catch (Exception e) {
                e.printStackTrace();
                throw new ClassNotFoundException();
            }
        }

        @Override
        protected Class<?> loadClass(String name, boolean resolve) throws ClassNotFoundException {
            synchronized (getClassLoadingLock(name)) {
                Class<?> c = findLoadedClass(name);
                if (c == null) {
                    c = findClass(name);
                }

                if (resolve) {
                    resolveClass(c);
                }
                return c;
            }
        }

    }
        public static void main(String args[]) throws Exception {
            //初始化自定义类加载器，会先初始化父类 ClassLoader，其中会把自定义类加载器的父加载 器设置为应用程序类加载器 AppClassLoader
            MyClassLoader classLoader = new MyClassLoader("D:/test");
            //D盘创建 test/com/tuling/jvm 几级目录，将 User 类的复制类 User1.class 丢入该目录
            Class clazz = classLoader.loadClass("com.tuling.jvm.User1");
            Object obj = clazz.newInstance();
            Method method = clazz.getDeclaredMethod("sout", null);
            method.invoke(obj);
            System.out.println(clazz.getClassLoader().getClass().getName());
