如何解决名称冲突有相同的擦除？

Question

I have this problem by this moment, I got a class with two methods with the same erasure:

public class VO implements Map<String,String> , Serializable{

    public synchronized String put (Object key, Object value){

       if (key == null)

           return null;

       if (value == null)
           return remove(key);
       String stringKey = key.toString();

       String stringValue = value.toString();

       if (value instanceof Boolean)
            stringValue = ((Boolean)value) ? "Y" : "N";

       return put(stringKey,stringValue);
}

@Override
public synchronized String put (String key, String value)
{
    if (key == null)
        return null;
    if (value == null)
        return remove(key);
    //
    int index = m_keys.indexOf(key);
    if (index != -1)
        return m_values.set(index, value);
    m_keys.add(key);
    m_values.add(value);
    return null;
   }    //  put
 }

Both methods are used by this app a lot, I can't change the name of any and I can't delete put(Object key, Object value) method, any ideas how I can fix this?

@Aris_Kortex well firts of all, VO is used a LOT, to create the UImodel of this application and the constructor of VO is this:

public VO (Map<String,String> map)
   {
    this();
    Iterator<String> it = map.keySet().iterator();
    while (it.hasNext())
    {
        Object key = it.next().toString();
        Object value = map.get(key);
        put (key, value);
    }
}   //  VO

/** Base SerVersion */
private static final long serialVersionUID = 8683452581122892189L;

/** Keys            */
private ArrayList<String>   m_keys;
/** Values          */
private ArrayList<String>   m_values;
/** Embedded VOs    */
protected ArrayList<VO>     p_vos = null;

then i am affraid i can't measure the impact of changing something here...i need to create a package of this proyect that i refactoriced because before was a mess..but maven throw me that error...
