Cucumber Parallel Testing giving weird results - maven

Question

I'm trying to run my cucumber project (two runner classes) in parallel browsers and I am getting weird results. When I do a mvn verify, first it will run each runner class sequentially. The first will pass and the second will fail due to the following error -
org.openqa.selenium.NoSuchSessionException: Session ID is null. Using WebDriver after calling quit()?
Then right after, it will run both runner classes in parallel (like I want it to), and all will pass just fine. And maven will report the Build Success.
I am not initializing the webdriver in the #Before annotation. Instead I am using cucumber-picocontainer dependency injection right into my step definition classes. I have tried swapping driver.close() and driver.quit() in my #After annotation, but that didn't change the results. Please find some code snippets below and then my POM. Many thanks in advance.
public class GivenSteps {
WebDriver driver;
CustomWaits waits;
public GivenSteps(DependencyInjection dependencyInjection) {
this.driver = dependencyInjection.getDriver();
this.waits = dependencyInjection.getWaits();
}
Hooks -
public class Hooks {
WebDriver driver;
public Hooks(DependencyInjection dependencyInjection) {
this.driver = dependencyInjection.getDriver();
}
#Before("#setup")
public void setUp() {
driver.manage().deleteAllCookies();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(20, TimeUnit.SECONDS);
}
#After("#destroy")
public void tearDown() throws Throwable {
//driver.close();
driver.quit();
}
Dependency Injection -
public class DependencyInjection {
private static String browserType = Settings.BROWSER.getValue();
private static WebDriver driver = null;
private static CustomWaits waits = null;
public WebDriver getDriver() {
if (driver == null) {
driver = utilities.DriverFactory.createDriver(browserType);
}
return driver;
}

Answer 1

I had to comment out the section in my POM.xml -> maven-surefire-plugin because now I am only using maven-failsafe-plugin
Originally I had both active in my POM, so both were running sequentially.
