使用通过JAVA代码生成的令牌时，oauth的凭据无效（失败）

Question

我试图使用oauth访问我的收件箱，当我使用使用JAVA代码生成的令牌时，总是会出现无效凭据错误。我正在使用IMAP并传递oauth令牌以获得身份验证。但是，当我使用python生成令牌并在代码中使用该令牌时，它可以很好地从我的收件箱中获取电子邮件

以下是使用IMAP的代码片段：

public static IMAPSSLStore connectToImap(String host,
                                          int port,
                                          String userEmail,
                                          String oauthToken,
                                          String oauthTokenSecret,
                                          OAuthConsumer consumer,
                                          boolean debug) throws Exception {
   Properties props = new Properties();
   props.put("mail.imaps.sasl.enable", "true");
   props.put("mail.imaps.sasl.mechanisms", "XOAUTH");
   props.put(XoauthSaslClientFactory.OAUTH_TOKEN_PROP,
             oauthToken);
   props.put(XoauthSaslClientFactory.OAUTH_TOKEN_SECRET_PROP,
             oauthTokenSecret);
   props.put(XoauthSaslClientFactory.CONSUMER_KEY_PROP,
             consumer.consumerKey);
   props.put(XoauthSaslClientFactory.CONSUMER_SECRET_PROP,
             consumer.consumerSecret);
   Session session = Session.getInstance(props);
   session.setDebug(debug);

   final URLName unusedUrlName = null;
   IMAPSSLStore store = new IMAPSSLStore(session, unusedUrlName);
   final String emptyPassword = "anonymous";

   store.connect(host, port, userEmail, emptyPassword);
   return store;
 }

这是错误日志-

有没有办法从JAVA代码中正确生成令牌。我的实际需求是使用我的iPad客户端生成令牌，并在服务器中使用该令牌获取电子邮件。任何帮助都是非常感谢的

我们使用http://pastebin.com/kwcZQcvj来创建令牌和密码
