Selenium java.net.SocketException: Connection reset when calling driver.quit();

I saw these threads:
java.net.SocketException: Connection reset on Selenium driver.close() or driver.quit() statements
selenium/java- java.net.SocketException: Connection reset
But I still don't understand the issue here. Everything is working fine, I get the response and content from the website and when I'm done I call the driver.quit(); / driver.close(); and get the exception. If I don't call that .quit(); I don't get the exception.
I get this exception after I get the web scraping content:

This is the code from the main:
String url = "https://relatedwords.org/relatedto/";
System.setProperty("webdriver.chrome.driver", filePath);
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--headless");
WebDriver driver = new ChromeDriver(chromeOptions);
driver.get(url + "Fishsticks");
WebElement words = driver.findElement(By.className("words"));
final List<WebElement> wordList = words.findElements(By.tagName("a"));
wordList.forEach(word -> System.out.println(word.getText()));
// when I remove this I do not get any exceptions
driver.quit();
I use the latest chrome version I just checked, and there are no updates available (Version 109.0.5414.120) and I am using chrome driver version ChromeDriver 109.0.5414.74 and the latest selenium version 4.8.0
So what is the solution here? I tried to read so many stack threads but have not found any solution

Below is the same code I have tried and it works fine with no exceptions. Only difference is that I have not added following code System.setProperty("webdriver.chrome.driver", filePath);. You do not need to set property when you are using the latest version of selenium(which you are using anyways). Try removing this line and see if it resolves your issue.
public static void main(String[] args){
ChromeOptions options = new ChromeOptions();
options.addArguments("--headless");
WebDriver driver = new ChromeDriver(options);
driver.get("https://relatedwords.org/relatedto/" + "Fishsticks");
WebElement words = driver.findElement(By.className("words"));
final List<WebElement> wordList = words.findElements(By.tagName("a"));
wordList.forEach(word -> System.out.println(word.getText()));
driver.quit();
}

java.net.SocketException: Connection reset
java.net.SocketException may occur due to several possible reasons as follows:
It can occur on the server-side when the client closed the socket connection before the response could be returned over the socket. For example, by quitting the browser before the response was retrieved.
It can also occur by writing to a connection that the other end has already closed normally resulting in an application protocol error.
This usecase
I took your program and executed it. Here is the result:
Code block:
System.setProperty("webdriver.chrome.driver", "C:\\BrowserDrivers\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
WebDriver driver = new ChromeDriver(options);
driver.get("https://relatedwords.org/relatedto/Fishsticks");
WebElement words = driver.findElement(By.className("words"));
final List<WebElement> wordList = words.findElements(By.tagName("a"));
wordList.forEach(word -> System.out.println(word.getText()));
driver.quit();

Conclusion
Programmatically, I don't see any error in your code block. However ensure that:
JDK is upgraded to current levels JDK 8u351.
Selenium is upgraded to current levels Version 4.8.0.
ChromeDriver is updated to current ChromeDriver v109.0 level.
Chrome Browser is updated to current chrome=109.0 (as per chromedriver=109.0.5414.74 release notes).
Take a System Reboot.
Execute your Test as a non-root user.

java.lang.NoClassDefFoundError: org/openqa/selenium/ElementNotSelectableException

This issue is occuring for new projecting. Old projects are working fine.Though I am copying the same data from old project to new project.

driver.manage().window().maximize();
driver.get(props.getProperty("url"));

It was Dependency issue.Though I had added selenium dependencies in pom.xml file but it did not get added successfully.
So issue was occuring.
If you also get this issue,
Open terminal, navigate till path of the project and execute command "mvn install"
and then run your program.

Cucumber step definitions not linked

I upgraded my serenity and cucumber tests today to version 2.6.0 en cucumber 6. Only to have a lot of package needed to change and the steps of my feature files no longer linked to the step definitions. If if this setup for my cucumberrunner
import io.cucumber.junit.CucumberOptions;
import net.serenitybdd.cucumber.CucumberWithSerenity;
import org.junit.runner.RunWith;
#RunWith(CucumberWithSerenity.class)
#CucumberOptions(features = {"src/test/resources/features"},
glue = {"be.nbb.hive.cucumber.steps"})
public class CucumberRunner {
}
But if I look in intellij in the feature files you can no longer click through the steps to go to the definition. And when I run a feature file I get following exception:

I'm not sure what is going wrong as the same code worked with the previous version

This is a question related to upgrading to Cucumber 6, which has a different API, syntax and and architecture compared to Cucumber 2. You will need to rewrite many of the step definition methods, as the regular expressions used in Cucumber 2 will need updating, and the parameter conversion logic will also need updating (different classes are used).

Unable to open Browser in Selenium

I am running simple code in selenium and it throws below exception:-
#Test
public void test(){
System.setProperty("webdriver.chrome.driver", "geckodriver.exe");
WebDriver driver=new FirefoxDriver();

driver.manage().window().maximize();
}
Following error is shown when I have executed my script:
Previously it was working, my firefox version is 55 and i am using latest gecko driver version. Please help!!

You are using wrong syntax near "System.setProperty("webdriver.chrome.driver", "geckodriver.exe");". Replace "chrome.driver" with "gecko.driver"
#Test public void test(){
System.setProperty("webdriver.chrome.driver", "geckodriver.exe");
WebDriver driver=new FirefoxDriver();
driver.get("https://google.com");
driver.manage().window().maximize();
}
Replace it with
#Test public void test(){
System.setProperty("webdriver.gecko.driver", "geckodriver.exe");
WebDriver driver=new FirefoxDriver();
driver.get("https://google.com");
driver.manage().window().maximize();
}

The error
Exception is:- java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)V at
is Java's way of telling you that your code is internally invoking a method called
void checkState(boolean, java.lang.String, java.lang.Object)
within the class com.google.common.base.Preconditions but this method is not available.
This usually happens when your classpath is messed up.
You haven't mentioned what version of Selenium you are working with. So I am going to assume that you are working with the latest released version of Selenium viz., 3.5.2.
Please make sure that you are using com.google.guava:guava version 23.0.
If you are using Maven, then you can perhaps add a dependency which looks like below, to your pom file.
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>23.0</version>
</dependency>

it's conflict problem, you should check on Project Structure, if it exists 2 Maven, it's conflict problem, you have to delete "Maven: com.google.guava: guava:jdk...". If it exists only 1 Maven guava, just need update the dependency

I use selenium-java-2.40.0 and Firefox 26.
But the following code works:
WebDriver driver = new FirefoxDriver();
driver.get("http://myhostname:myport/myapplicationname");
WebElement userId = driver.findElement(By.name("userId"));
userId.sendKeys("coolusername");
WebElement password = driver.findElement(By.name("password"));
password.sendKeys("ultrasecretpassword");
password.submit();
System.out.println("Page title is: " + driver.getTitle());
driver.quit();
So it is not a problem of Selenium version compatibility with Firefox.
Selenium tries to find some servlet at this URL:
http://localhost:4545/selenium-server/driver/
But receives a 404 error.
Ca you help me?

Ensure that the Firefox is installed in the default location. Optional you can give the absolute path to the browser:
String browserString = "c:\\program files\\mozilla firefox\\firefox.exe";
Check the source and documentation for more information.
However, I recommend to use the Driver (like in the working sample), if you don't want to provide a Selenium RC.

Looking at the source code of the DefaultSelenium class, you can notice that the alloweb browser strings are:
*webdriver
*firefox-wd
*iexplore-wd
So I wrote:
String browserString= "*firefox-wd";
And that fixed the problem.
