eclipse上运行Selenium脚本打开火狐后显示URL无效

eclipse里selenium-java-2.53.0.jar跟selenium-server-standalone-2.53.0.jar两个包都导进去了,试运行代码如下:
package TestProject;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class TestProject01 {
public static void main(String args[]){
WebDriver driver = new FirefoxDriver();
driver.get("http://www.baidu.com/");
}
}
火狐能正常弹出,但是显示此URL无效
请问该如何解决?

java.lang.ExceptionInInitializerError,这个错误意思是静态初始化程序中发生意外异常的信号。抛出 ExceptionInInitializerError 表明在计算静态初始值或静态变量的初始值期间发生异常。
