修改ClassLoader的加载机制会如何？
假如在ClassLoader中做如下的修改：

public class ClassLoader{   private List<ClassLoader> subClassLoaderList = new ArrayList<ClassLoader>();//新增成员   //新增方法   //注册一个ClassLoader   public void registSubClassLoader(ClassLoader loader){        subClassLoaderList.add(loader);   }   //修改方法的实现   public Class<?> findClass(String className)throws ClassNotFoundException{       try{        return findClass(className,false);       }catch(ClassNotFoundException e){         for(ClassLoader cl : subClassLoaderList){             try{              return cl.findClass(className,false);             }catch(ClassNotFoundException e){             }         }       }       throw new ClassNotFoundException(className);   }}
