title: Xstream no-args constructor error
body: <p>I'm getting the following error when it tries to create an instance of 'Transacao'</p>
  
  <pre><code>`Error: Cannot construct br.com.cbmp.ecommerce.resposta.Transacao as it does not have a no-args constructor : Cannot construct br.com.cbmp.ecommerce.resposta.Transacao as it does not have a no-args constructor `

  <p>I am aware that there's a bug with XStream 1.3.1 and JDK7, but I'm currently using XStream 1.3.1 and <strong>JDK6</strong>. Any ideas why this error is still happening?</p>
  
  <p>Thanks</p>
