STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
//Execute below code

import java.util.HashMap;
import java.util.Map;
import java.util.Set;

public class Testmap {

    
    public Testmap() {
        
    }
    
    protected void testMap() {
        MyMap myMap = new MyMap();
        myMap.put("A", "VVVV");
        System.out.println(myMap.clone());
        System.out.println(myMap.get("A"));
    }
    
    
    public class MyMap extends HashMap {
        
        Map map = new HashMap();
        
        public MyMap() {
            
        }
        
        @Override
        public Object put(Object key, Object value) {
            return map.put(key, value);
        }
        
        @Override
        public Object get(Object key) {
            return map.get(key);
        }
        
        @Override
        public Object clone() {
            return super.clone();
        }

        @Override
        public Set entrySet() {
            return map.entrySet();
        }
        
    }
    /**
     * @param args
     */
    public static void main(String[] args) {
        Testmap test = new Testmap();
        test.testMap();
    }

}


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It was working properly in earlier java7 versions.
ACTUAL -
