Java 我可以同时在不同的端口上运行selenium server吗？

我看到了关于如何在两个不同端口上运行SeleniumWebDrive服务器的内容

我尝试过这样做：

 java -Dwebdriver.chrome.driver=./chromedrive -jar selenium-server-standalone-2.44.0.jar -port 4445

 java -Dwebdriver.chrome.driver=./chromedrive -jar selenium-server-standalone-2.44.0.jar -port 4444

并运行调用端口4445上的服务器的代码

但我有一个例外：
