icloud connect A0 BAD Parse Error

Question

用于连接的代码：

Properties properties = System.getProperties();
properties.setProperty("mail.store.protocol", "imaps");
properties.setProperty("mail.imap.starttls.enable", "true");
String host = "imap.mail.me.com";
int port = 993;

String result = null;
TestLogger.log("Connecting to Imap..");
try {
    //Connect to the server

    Session session = Session.getInstance(properties);
    session.setDebug(true);
    Store store = session.getStore();
    store.connect(host, port, "username","pass");

store.connect抛出A0 BAD Parse Error，完整的调试输出：
