Erro ao tentar executar uma Ação depois de fazer a melhoria do controlador

Usando Java 17 e Tomcat 9 Servlet:

package br.com.arthur.gerenciador.servlet;

import java.io.IOException;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import br.com.arthur.gerenciador.acao.Acao;


@WebServlet("/entrada")
public class UnicaEntradaServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        String paramAcao = request.getParameter("acao");

        //String packageAction = "br.com.alura.gerenciador.acao.";

        String nomeDaClasse = "br.com.alura.gerenciador.acao." + paramAcao;

        String nome;
        try {
            Class classe = Class.forName(nomeDaClasse); 
            Acao acao = (Acao) classe.newInstance();
            nome = acao.executa(request,response);
        } catch (ClassNotFoundException | 
                InstantiationException | 
                IllegalAccessException e) {
            throw new ServletException(e);
        }

        String[] tipoEEndereco = nome.split(":");
        if(tipoEEndereco[0].equals("forward")) {
            RequestDispatcher rd = 
                request.getRequestDispatcher("WEB-INF/view/" + tipoEEndereco[1]);
            rd.forward(request, response);
        } else {
            response.sendRedirect(tipoEEndereco[1]);
        }        
    }

}

Interface:

package br.com.arthur.gerenciador.acao;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public interface Acao {
