BOSH connection not closed while disconnect()

As per the code Smack/XMPPBOSHConnection.java at master · igniterealtime/Smack · GitHub

at line number 290 there should be a client closing code

but the client close code only exists in the connect() function and no where else it is called

this leads the client to stay connected until the main thread terminates

Introduce a private function saying close()

and put

---------------------------

if (client != null) {

       client.close();

       client = null;

}

---------------------------

and call it at both connect() as well as shutdown() functions
