如何使用FirefoxDriver关闭java中的selenium控制台日志记录？

Question

我在使用selenium网络驱动程序时试图关闭eclipse中的记录器。

    FirefoxProfile profile = new FirefoxProfile();       
    profile.setPreference("webdriver.log.driver", "ERROR");

    WebDriver driver = new FirefoxDriver(profile);

在运行程序时，我仍然收到这些调试日志：

[DEBUG] 2015-04-10 12:10:39,904
CookieSpec selected: best-match

[DEBUG] 2015-04-10 12:10:39,922
Auth cache not set in the context

[DEBUG] 2015-04-10 12:10:39,925

[DEBUG] 2015-04-10 12:10:39,969
Opening connection {}->http://127.0.0.1:7056

有什么方法可以关掉它们吗？
