data :，当我执行以下Selenium ChromeWebdrive脚本时，会在chrome网址栏中显示。是因为其他Chrome浏览器实例正在运行？

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class ChromWebdriverWindows {

    public static void main(String[] args) {
        //String url = "https://www.google.co.in/";
        System.getProperty("webdriver.chrome.driver", "C:\\Automation\\chromedriver_win32\\chromedriver.exe");
        WebDriver drive;
        drive = new ChromeDriver();
        drive.get("https://www.flock.co");
    }

}

在控制台中出现此错误：
