标题: 为什么总是抱错Caused by: java.net.SocketException: Connection reset
背景：我编写的一段小代码Java Selenium WebDriver，完成[打开页面]-〉[用户登入]-〉[用户登出]的简单工作。

问题：程序运行很不稳定。表现为同样的代码，运行若干次，仅有一两次等成功。其余几乎报同样的错误：
Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Error communicating with the remote browser. It may have died.

分析：
一开始认为可能是WebDriver和Firefox的版本搭配有问题，就尝试将配置从WebDriver 2.44.0+Firefox 33.1.1+JDK 1.6.0_45，修改为WebDriver 2.39.0+Firefox 25.0.1+JDK 1.6.0_45。但遗憾的是，情况依旧。
从错误信息分析，理解是socket连接被复位，导致Firefox到WebDriver无法继续通信。但不知道这个问题改如何确定和解决，希望有相关经验的同仁指点迷津。

代码：
package local.webdriver;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
public class WebDriverDemo {
public static void main(String[] args) throws InterruptedException {

  WebDriver driver=new FirefoxDriver();

  driver.get("http://www.claimsecure.com/en-CA/products/OnlineServices.aspx");

  driver.manage().window().maximize();

  // type in Username
  Thread.sleep(5000);
  driver.findElement(By.name("pin")).sendKeys("username");  //在此暂时屏蔽真实用户名

  // type in password
  driver.findElement(By.name("pwd")).sendKeys("password"); //在此暂时屏蔽真实口令

  // click 'Login' button
  driver.findElement(By.id("ctl00_cphMainContent_ucOSLoginBox_SignInButton")).click();

  // click 'Log off' button
  driver.findElement(By.id("ctl00_hlnkLogOff")).click();

  driver.quit();
}
}

WebDriver driver=new FirefoxDriver();

实例化driver不对
