If I use this line my test works fine:
            driver = new RemoteWebDriver(
                    new URL("http://localhost:4444/wd/hub"),
                    DesiredCapabilities.firefox());


            If I use this line I get the error below:
            driver = new RemoteWebDriver(
                    new URL("http://localhost:4444/wd/hub"),
                    DesiredCapabilities.internetExplorer());
