about keepAlive() function

[THEONE10211024]

In keepAlive() function in PushService line 292, as we can see: if "mConnection.sendKeepAlive();" this line throws a MqttException Exception and catched by the exception block, we will cancle both KEEP_ALIVE alarm and RECONNECT alarm.Thus we will lose connection with the server forever! And will not reconnect at some point in the future. What I'm worried is the CLIENT will completely lose connection with the SERVER forever? Am I right and how to figure out the problem?
