我正在尝试按照以下网站上显示的协议，了解如何在JavaMail上实施GmailMsgIdTerm。
https://javamail.java.net/nonav/docs/api/com/sun/mail/gimap/package-summary.html
但是，它会不断连接到正确的文件夹（例如[Gmail] /所有邮件），但无法根据作为GmailMsgId输入的Long值找到邮件。
我初始化一个名为foundMessages的消息[]，然后运行：
foundMessages = folder.search(new GmailMsgIdTerm(<long value>));
我知道，使用原始IMAP命令时，此Gmail邮件ID存在。我怎么能用JavaMail做到这一点？
调试输出如下，然后是自定义的Exception，告诉我Message数组包含0个项目。
