"org.openqa.selenium.NoSuchSessionException: invalid session id" when running tests with invocationCount attribute

[mycheap...@gmail.com]

Hello,

@Test(invocationCount = 3, threadPoolSize = 3)
public void test1() throws InterruptedException {
System.out.println("Test 1");
WEBDRIVER_THREADLOCAL.get().get("https://www.google.com/");
Thread.sleep(3000);
System.out.println("title is " + WEBDRIVER_THREADLOCAL.get().getTitle());
}

BaseTest

public WebDriver driver;
public static ThreadLocal<WebDriver> WEBDRIVER_THREADLOCAL = new ThreadLocal<WebDriver>();

@BeforeMethod
public void launch() throws MalformedURLException {
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--remote-allow-origins=*");
System.setProperty("webdriver.chrome.driver", ".//resources//chromedriver.exe");
driver = new ChromeDriver(chromeOptions);
WEBDRIVER_THREADLOCAL.set(driver);
driver.manage().window().maximize();
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

@AfterMethod
public void afterSuite() {
WEBDRIVER_THREADLOCAL.get().close();
}

Console:

Test 1
Test 1
Test 1
title is Google
title is Google

// Could not get the third title.

I think I somewhat understand why I am getting this error. I am closing the browser at @AfterMethod, but because I am using THREADLOCAL, it should not close all the browsers. Currently, test can only get google title first two times and then all browsers get closed so I am getting the error when test tries to get the title third time. How can I close the browsers after test repeated 3 times? Thank you!
