Lỗi khi sử dụng Selenium 3

[nguyenpm.it (Nguyên Minh)]

Mình đang tìm hiểu về Selenium 3. Mình có đoạn code đơn giản như sau:
public class NavigateToAUrl {

public static void main(String[] args) {
	System.setProperty("webdriver.gecko.driver", "D:\\Driver\\geckodriver.exe");
	WebDriver driver = new FirefoxDriver();
	driver.get("http://www.google.com");
}

Mình chạy nó vẫn được. Nhưng ở Console nó báo
