When doing some sample codings with Java I came crosss ClassCast Exception, from where I cast the object to StaticClass. Can any explaing the what has happened here.

public void test5() throws Exception {

   System.out.println(StaticClass.obj);
   Object newInstance = ClassLoader.getSystemClassLoader().loadClass("com.StaticClass").newInstance();
   System.out.println(newInstance.getClass().getDeclaredField("obj").get(newInstance));

   Object newInstance2 = new ILoader().loadClass("com//StaticClass.class").newInstance();
   System.out.println(newInstance2.getClass().getDeclaredField("obj").get(newInstance2));

   StaticClass s = (StaticClass)newInstance2;
   System.out.println(s.obj);

   System.out.println(newInstance.getClass().getClassLoader());
   System.out.println(newInstance2.getClass().getClassLoader());



  }

package com;

public class StaticClass {

 public static final Object obj = new Object();
}

package com;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

public class ILoader extends ClassLoader {

 public ILoader() {
  super(null);
 }

 @Override
 protected Class<?> findClass(String name) throws ClassNotFoundException {

   File file = new File(name);

   byte[] bytes = new byte[(int)file.length()];

   try {
     new FileInputStream(file).read(bytes);
   } catch (FileNotFoundException e) {
    e.printStackTrace();
   } catch (IOException e) {
    e.printStackTrace();
   }



   return super.defineClass("com.StaticClass",bytes, 0, bytes.length);
 }
}

output which was given by last sysout's when the casting part of the code not existed is as belows.
