缺少';'在MimeMessage savechanges方法中

Question

我正在通过JavaMail API发送邮件。 源代码

 Properties props = new Properties(); 
     Session mailSession = Session.getDefaultInstance(props, null); 
     Message msg = new MimeMessage(mailSession); 
     msg.setFrom(new InternetAddress(Sender)); 
     String[] toAddresses = null; 
     toAddresses = addToRecepients(f_StrtoAdd, msg, toAddresses); 
     String[] ccAddresses = null; 
     ccAddresses = addCCRecepients(f_StrccAdd, msg, ccAddresses); 

     String[] bccAddresses = null; 
     bccAddresses = addBccRecepients(f_StrbccAdd, msg, 
       bccAddresses); 

     Multipart mp = formMsgContents(); 

     msg.setSentDate(new Date()); 
     m_log.warning(""+msg.getSentDate()); 
     msg.setContent(mp); 
     msg.saveChanges(); 

我得到msg.saveChanges异常（）; - 异常消息缺失“;”。
