Appium server not closing gracefully - Command failed to close cleanly. Destroying forcefully (v2)

Issues/Bugs

I’m running an Appium server programmatically with the following code:

public class AppiumTests {

private AppiumDriverLocalService service;
private AppiumServiceBuilder builder;
private DesiredCapabilities cap;
public static AppiumDriver<WebElement> driver;

public void startServer() {

    builder = new AppiumServiceBuilder();
    builder.withIPAddress("127.0.0.1");
    builder.usingPort(4728);

    service = AppiumDriverLocalService.buildService(builder);
    service.start();
}

public void stopServer() {
    service.stop();
}


public void mobileTest() throws MalformedURLException{


    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("deviceName", "Nexus 5");
    capabilities.setCapability("platformVersion", "7.1.1");
    capabilities.setCapability("browserName", "chrome");
    capabilities.setCapability("deviceOrientation", "portrait");

    driver = new AndroidDriver<>(new URL("http://127.0.0.1:4728/wd/hub"), capabilities);

// My test cases are here

}


public static void main(String[] args) throws MalformedURLException {
    AppiumServerJava appiumServer = new AppiumServerJava();

        appiumServer.startServer();
        appiumServer.mobileTest();
        appiumServer.stopServer();

}
}

When i run this the Appium server starts as expected but i get an info warning message as follows:

INFO: Command failed to close cleanly. Destroying forcefully (v2). org.openqa.selenium.os.UnixProcess$SeleniumWatchDog@3ac42916

Full output:

Any reason why this is happening? Certainly not sure why it’s being displayed twice before the Appium server is even started.
