AWSIotMqttClient 断开连接后应用程序不会停止

Question

我正在使用 AWSIotMqttClient 订阅和发布主题。收到所有消息后，我想停止我的应用程序。但它的工作时间无限长。这是一个无限工作的简单代码，即使没有订阅：

 SampleUtil.KeyStorePasswordPair keyStorePasswordPair =
                SampleUtil.getKeyStorePasswordPair("certificate.pem", "privateKey.pem");

        AWSIotMqttClient client = new AWSIotMqttClient(
                "mqtt-broker.address",
                "deviceID",
                keyStorePasswordPair.keyStore,
                keyStorePasswordPair.keyPassword);

        client.connect();
        client.disconnect();

这是我的日志：

    > Task :Application.main()
Cert file:certificate.pem Private key: privateKey.pem

我可以使用 System.exit(0) 停止我的申请，但这对我来说是不受欢迎的。我希望在所有代码通过后，应用程序将停止。
