…alled when there is no message broker (message broker service is down due to a failure, or address is incorrect...) For users who use the library, debugging is very difficult unless exceptions are thrown in such cases. Currently, if the message broker attempts to connect to a situation that does not exist, there is a risk of performing the next logic without any exceptions being returned. Of course, the getException() of the IMqttToken instance returned to the connect() call can be checked for an Exception, but it is difficult to use because it is not synchronized. I think it's right to make an exception in this particular case.
