JDK 8に電子メールサーバーを接続できません

Question

IMAPメールサーバーをjdk8からメールをフェッチするために接続できませんが、jdk7で正常に動作します。私はそれが以下store.connect(userName, password);

でハング上記のコードを実行しようとすると以下 は私のコード

private Properties getServerProperties(String protocol, String host, String port) { 
    Properties properties = new Properties(); 
    properties.put(String.format("mail.%s.host", protocol), host); 
    properties.put(String.format("mail.%s.port", protocol), port); 
    properties.setProperty(String.format("mail.%s.socketFactory.class", protocol), "javax.net.ssl.SSLSocketFactory"); 
    properties.setProperty(String.format("mail.%s.socketFactory.fallback", protocol), "false"); 
    properties.setProperty(String.format("mail.%s.socketFactory.port", protocol), String.valueOf(port)); 
    return properties; 
} 

public void getNewEmails(String protocol, String host, String port, String userName, String password) { 
    Properties properties = getServerProperties(protocol, host, port); 
    Session session = Session.getDefaultInstance(properties); 
    session.setDebug(true); 

    try { 
     Store store = session.getStore(protocol); 
     store.connect(userName, password); 

     Folder inbox = store.getFolder("INBOX"); 
     inbox.open(Folder.READ_WRITE); 

     int count = inbox.getMessageCount(); 
     Message[] messages = inbox.getMessages(1, count); 
     for (Message message : messages) { 

      Address[] fromAddresses = message.getFrom(); 
      System.out.println("..................."); 
      System.out.println("\t From: " + fromAddresses[0].toString()); 
      System.out.println("\t To: " + parseAddresses(message.getRecipients(RecipientType.TO))); 
      System.out.println("\t CC: " + parseAddresses(message.getRecipients(RecipientType.CC))); 
      System.out.println("\t Subject: " + message.getSubject()); 
      System.out.println("\t Sent Date:" + message.getSentDate().toString()); 
      System.out.println(message.getContent()); 
     } 
     inbox.close(false); 
     store.close(); 
    } catch (NoSuchProviderException ex) { 
     System.out.println("No provider for protocol: " + protocol); 
     ex.printStackTrace(); 
    } catch (MessagingException ex) { 
     System.out.println("Could not connect to the message store"); 
     ex.printStackTrace(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

} 

private String parseAddresses(Address[] address) { 

    String listOfAddress = ""; 
    if ((address == null) || (address.length < 1)) 
     return null; 
    if (!(address[0] instanceof InternetAddress)) 
     return null; 

    for (int i = 0; i < address.length; i++) { 
     InternetAddress internetAddress = (InternetAddress) address[0]; 
     listOfAddress += internetAddress.getAddress() + ","; 
    } 
    return listOfAddress; 
} 

である私は上記のコードhttp://www.developer.com/java/data/monitoring-email-accounts-imap-in-java.htmlを試みたところからのリンクです。 質問の答えがないリンクはこちら https://community.oracle.com/message/13244272#13244272

以下は両方のJDKで動作しているログです。

After Bill Shannon comment I tried below configuration and it start working with below configuration with JDK-8. 

`<dependency> 
<groupId>com.sun.mail</groupId> 
<artifactId>javax.mail</artifactId> 
<version>1.5.5</version> 
</dependency>`
