Selenium program doesn't stop running

Question

I am developing in VSCode with the Java Extension Pack (which includes Maven).

For some reason, my program (below) does not terminate after running.

import java.util.Scanner;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

Scanner in = new Scanner(System.in);
System.setProperty("webdriver.chrome.driver", "Path to exe\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.quit();

System.out.println("Press enter to quit");
in.nextLine();
in.close();

The Selenium chrome tab opens for a moment and then closes (as I would expect). The program then prompts me to "press enter", which I do, but the program does not end after that. It only ends if I press Ctrl-c (at which point it asks if I want to terminate the batch job).

If I comment out the Selenium stuff, it works fine - the program ends after I press enter. Below is a picture of the log:

Do you think the part about the log error could be the cause? That part is not there when I comment out the Selenium stuff. Also, I hope you don't mind I censored some personal information.

Please let me know if there is anything I can do to make this question easier to answer.

Update: I fixed the log issue by including the slf4j-jdk14 dependency but that didn't have any impact - the program still didn't shut down. The only difference now is that the log no longer contains the lines beginning with "SLF4J"

I have the exact same problem, and I am still researching the problem. However, I have fixed the issue by downgrading the Selenium-Java Maven-dependency from version 4.0.0-alpha-6 to version 3.141.59. My application is exiting as expected after the downgrade.

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.141.59</version>
    </dependency>

I will update my answer as I find out more.

This feels like more of a work-around than an answer, but if you add System.exit(0); at the end of the program then it exits (as you would expect). I don't know what about the Selenium code makes it necessary to do explicitly exit though.

This shouldn't be necessary. What version of Selenium are you using? By downgrading to the latest stable version, as I suggested below, I got my app exiting normally without adding explicit system exit. – dma Jul 11 '20 at 18:50
I am using 4.0.0-alpha-6. I will try downgrading – manissss Jul 13 '20 at 21:06
Did the downgrading help you? Would be very happy if you could select my reply below as the accepted answer. @manissss – dma May 16 '21 at 19:40
Well, downgrading fixed the issue but wasn't really an option for me since it broke other things. The issue ended up being resolved when they released newer versions. I can definitely accept your answer, I just don't know what the stack overflow protocol mandates in this situation: while your answer technically did solve the problem, it just wasn't the solution for my scenario. Let me know what you think. – manissss May 18 '21 at 21:00

Thanks @dma downgrading to 3.141.59 - did the trick and now my program is terminating

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-chrome-driver</artifactId>
    <version>3.141.59</version>
</dependency>
