Ler Arquivo XML e gerar bean

Olá, estou com o seguinte dificuldade para ler arquivo XML gerado pela Caelum, que é bem parecido com o arquivo gerado pela Bovespa, com a seguinte URL:
link XML Negociacoes`

Tenho a seguintes classe que os nomes ja se explicam

1- ClienteWebService

package com.caelum.argentum.ws;

import com.caelum.argentum.beans.Negociacao;

import com.caelum.argentum.reader.LeitorXML;

import java.io.IOException;

import java.net.HttpURLConnection;

import java.net.URL;

import java.util.List;

public class ClienteWebService {

private static final String URL_WEBSERVICE = 
   "http://argentumws.caelum.com.br/negociacoes";

public List<Negociacao> getNegociacoes() throws  IOException{
  
    HttpURLConnection connection = null;

    URL url = new URL(URL_WEBSERVICE);
    
    connection = (HttpURLConnection)url.openConnection();
     
    return new LeitorXML().carrega(connection.getInputStream());//passa um tipo INPUTSTREAM para parametro
    

}

}

2LeitorXML

package com.caelum.argentum.reader;

import com.caelum.argentum.beans.Negociacao;

import com.thoughtworks.xstream.XStream;

import com.thoughtworks.xstream.io.xml.DomDriver;

import java.io.InputStream;

import java.util.List;

public class LeitorXML {

public LeitorXML(){
    
}

public List<Negociacao> carrega(InputStream inputStream) {
    
    XStream stream = new XStream(new DomDriver());
    //stream.alias("negociacao", Negociacao.class);
    List<Negociacao> listaDeXml =(List<Negociacao>) stream.fromXML(inputStream);
    return  listaDeXml;
    
 
}

}

3- E ainda a classe Test LeitorXMLTest(teste falhou)

package com.caelum.argentum.reader;

import com.caelum.argentum.beans.Negociacao;

import java.io.ByteArrayInputStream;

import java.io.InputStream;

import java.util.List;

import static junit.framework.Assert.assertEquals;

import org.junit.Test;

public class LeitorXMLTest {

public LeitorXMLTest(){
    
}

@Test
public void carregaXmlComUmaNegociacaoEmListaUnitaria(){
String xmlDeTeste = "<list>" +
      "  <negociacao>" +
      "    <preco>43.5</preco>" +
      "    <quantidade>1000</quantidade>" +
      "    <data>" +
      "      <time>1322233344455</time>" +
      "    </data>" +
      "  </negociacao>" +
      "</list>";
        
        
LeitorXML leitor = new LeitorXML();

InputStream xml = new ByteArrayInputStream(xmlDeTeste.getBytes());

List<Negociacao> negociacoes = leitor.carrega(xml);

assertEquals(43.5, negociacoes.get(0).getPreco(), 0.000001);

}

}

Ao rodar a classe teste segue o seguinte erro:expressionless:
