是否有可能变换子类中字段的最终修饰符

Question

情况就是这个

class Immutable
{
    public final int myField;

    public Immutable(int value)
    {
        myField = value;
    }

    //methods that treat the object as immutable
}

class Mutable extends Immutable
{
    //no longer final. The same field. Not subclass hiding superclass field.
    public int myField;

    //more methods, these mutate the state of the object
}

这可以用Java完成吗？甚至语言扩展？随着演员和所有。
