How to override the javadoc for a final method in a sub class?

public class BaseClass {
    /**
     * Gets the value.
     */
    public final String getValue() {
        // returns something.
    }
}

public class SubClass extends BaseClass {
    /**
     * Gets the value.
     * <p/>
     * The value is meaningless for SubClass.
     */
    @Override // Cannot override final method
    public final String getValue() {
        super.getValue(); // Not overriding implementation, just javadoc
    }
}

I do not need to change the implementation of the final method, I just want to change the Javadoc for it.
