Kill chromedriver process in Selenium / Java

I am currently running multiple Java programs through Jenkins using "Build Periodically" option and uses H 06 * * 1-5 (run it every day between 6 AM and 7 AM from Monday to Friday).

There are certain programs in which i click on Links which opens up a new window. Hence, I use the below Code

driver.findElement(By.xpath(".//*[@id='terms']/li[1]/a")).click();System.out.println("Home Page is loaded Successfully and Terms of Use Link is clicked");ArrayList<String> window1 = new ArrayList<String>(driver.getWindowHandles());driver.switchTo().window(window1.get(1));Thread.sleep(3000);driver.close();Thread.sleep(3000);driver.switchTo().window(window1.get(0));

Now after the program runs, My other program following this fails because of the ChromeDriver.exe process that is already running.

I tried using driver.quit() instead of driver.close() in the code above, but it will close my entire browser.

Note: I have used driver.quit() at the end of my program which doesn't help me getting rid of the running Chromedriver.exe instance opened when i switched window.

Please suggest me a a good way to handle this issue. I have been looking for this solution in JAVA. But mostly i see answers for C#.

Thanks
