一、问题描述
在JAVA FX中使用jxbrowser，第一次打开一个窗口，然后又打开一个窗口就出现如下错误：

代码如下：
BrowserContextParams params = new BrowserContextParams("D:\\IDEA_work\\javafx\\jxbrowser\\cookie");BrowserContext context = new BrowserContext(params);Browser browser = new Browser(context);BrowserView view = new BrowserView(browser);JFrame frame = new JFrame();frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);frame.add(view, BorderLayout.CENTER);frame.setSize(800, 600);frame.setLocationRelativeTo(null);frame.setVisible(true);browser.loadURL("");CookieStorage cookieStorage = browser.getCookieStorage();// Create and add new cookieint oneHourInMilliseconds = 36000000;int microsecondsOffset = 1000;// Cookie will be alive during one hour starting from nowlong expirationTimeInMicroseconds = (System.currentTimeMillis() +oneHourInMilliseconds) * microsecondsOffset;// cookieStorage.setCookie("", "mycookie", "myvalue",//".", "/", expirationTimeInMicroseconds, false, false);List<Cookie> cookies = cookieStorage.getAllCookies();for (Cookie cookie : cookies) {System.out.println("cookie = " + cookie);}
二、解决方法
这是由于浏览器使用相同配置文件目录造成的，也就是上面的BrowserContext，多次初始化时，使用的都是BrowserContext这一个用的是同一个目录。官网提供了一个解决方法：https://jxbrowser./support/solutions/articles/9000012878-creating-browser
多个窗口浏览时，初始化Browser时使用不同的目录就行了。
