Creates a HttpsServer instance which is initially not bound to any local address/port. The HttpsServer is acquired from the currently installed HttpServerProvider.

Create a HttpsServer instance which will bind to the specified InetSocketAddress (IP address and port number). A maximum backlog can also be specified. This is the maximum number of queued incoming connections to allow on the listening socket. Queued TCP connections exceeding this limit may be rejected by the TCP implementation. The HttpsServer is acquired from the currently installed HttpServerProvider. The server must have a HttpsConfigurator established with setHttpsConfigurator(HttpsConfigurator). 
Params:
addr – the address to listen on, if null then HttpServer.bind(InetSocketAddress, int) must be called to set the address
backlog – the socket backlog. If this value is less than or equal to
              zero, then a system default value is used.
Throws:
BindException – if the server cannot bind to the requested address,
         or if the server is already bound
