How to programmatically restart webpack dev server (is the close method just broken?)

Question

I am running a webpack dev server (v 1.16) like this

let compiler = webpack(webpackConfig);
let webpackServer = new webpackDevServer(compiler);
webpackServer.listen(program.webpackPort);

I want to make changes to the entry points and restart the server. I saw the invalidate method, but the only way I saw this was to call compiler.apply and then server.invalidate () and compiler.apply seem to accept the plugin.

I also saw the close method, but this does not seem to work. If I close it without changing the entry point, it seems to restart correctly. But as soon as I add the first, closing no longer has any effect (and does not display the console). This is how I used the close method.

if(shouldRestart){
    webpackConfig.entry = newEntry;
    webpackServer.close(); //same reference to server as above
    compiler = webpack(webpackConfig);
    webpackServer = new webpackDevServer(compiler);
    webpackServer.listen(program.webpackPort);
}

Server.prototype.close = function(callback) {
  this.sockets.forEach(function(sock) {
     sock.close();
  });
  this.listeningApp.close(function() {
     this.middleware.close(callback);
  }.bind(this));
 this.sockets = [];

webpack-dev-middleware, invalidate:

webpackServer.middleware.invalidate()
