java-client's NewSessionPayload.class conflict with selenium's NewSessionPayload.class

OS: Windows 10 Selenium Version: 3.9.1 Browser: Firefox Browser Version: 59.0.2 (64-bit)

Expected Behavior

• When start Firefox driver will call class NewSessionPageload.java of selenium instead call NewSessionPageload.java of java-client.

Actual Behavior

• When start Firefox driver called class NewSessionPageload.java of java-client instead call NewSessionPageload.java of selenium.
• Error message. Exception in thread “main” org.openqa.selenium.InvalidArgumentException: firefox_profile is not the name of a known capability or extension capability

Steps to reproduce

• Please run source code to reproduce :

   public class FirefoxTest {
	public static void main(String[] args) {
         // declaration and instantiation of objects/variables
        System.setProperty("webdriver.gecko.driver", "/path/to/geckodriver_win64.exe");          
        FirefoxProfile ffprofile = new FirefoxProfile();
    	FirefoxOptions firefoxOptions = new FirefoxOptions();
    	firefoxOptions.setProfile(ffprofile);
	WebDriver driver = new FirefoxDriver(firefoxOptions);
        String baseUrl = "http://demo.guru99.com/test/newtours/";
        String expectedTitle = "Welcome: Mercury Tours";
        String actualTitle = "";
        driver.get(baseUrl);
        // get the actual value of the title
        actualTitle = driver.getTitle();
        /*
         * compare the actual title of the page with the expected one and print
         * the result as "Passed" or "Failed"
         */
        if (actualTitle.contentEquals(expectedTitle)){
            System.out.println("Test Passed!");
        } else {
            System.out.println("Test Failed");
        }     
        //close Fire fox
         driver.close();
           }
       }

• This is a bug of java-client?
• Do Anyone have the workaround for this issue? Please advice me. Thank in advance!

[TikhomirovSergey]

Yes. I could reproduce this error. It seems something was broken because we did not test it on desktop browser.

[TikhomirovSergey]

The fix was merged. It is going to be published soon.
