Selenium does not execute in Java ExecutorService

[LusciousPear]

Meta -

OS: Ubuntu 16.04

Selenium Version: 3.0.1

Browser: Chrome

Browser Version: 55.0.2883.75 (64-bit)

Expected Behavior -

Multiple Chrome windows should open.

Actual Behavior -

No Chrome windows open.

Steps to reproduce -

I'm unable to get Selenium+ChromeDriver working inside an ExecutorService. This is so I can run multiple processes. It works just fine if I run it as a JUnit test inside a single thread.

There are no errors -- it runs fine until the WebDriver driver = new ChromeDriver(), and then just quits. No exceptions thrown.

To reproduce, just execute doPool().

    @Test
    public void doPool(){

        ExecutorService executor = Executors.newFixedThreadPool(10);

            executor.submit(() -> {

                testGoogleSearch();
            });

    }

    @Test
    public void testGoogleSearch() {
        //System.setProperty("webdriver.chrome.driver", "/path/to/chromedriver");

        String threadName = Thread.currentThread().getName();
        System.out.println("Hello " + threadName);

        WebDriver driver = new ChromeDriver();
        driver.get("http://www.google.com/xhtml");
        try {
            Thread.sleep(5000);  // Let the user actually see something!

            WebElement searchBox = driver.findElement(By.name("q"));
            searchBox.sendKeys("ChromeDriver");
            searchBox.submit();
            Thread.sleep(5000);  // Let the user actually see something!

            screenshot(driver);
        }
        catch (InterruptedException e) {
            e.printStackTrace();
        }

    }

@Test
public void doPool(){
    ExecutorService executor = Executors.newFixedThreadPool(10);
    executor.submit(() -> { testGoogleSearch();  });
    try {
        executor.awaitTermination(60, TimeUnit.SECONDS);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

and don't forget to quit the driver.
