A Java Exception has occurred.

Sempre que tento rodar a aplicação, o sistema exibe o erro "A Java Exception has occurred.". Percorri todos os tópicos, fiz tudo o que foi sugerido aos outros, mas nenhum solucionou meu problema. Abaixo, segue o código:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.DesiredCapabilities;


public class TesteAutomatizado {

    public static void main(String[] args) {

            System.setProperty("webdriver.gecko.driver", 
                    "C:\\Users\\Fernanda\\Desktop\\Cursos TI\\ALURA\\Selenium\\geckodriver.exe");
            System.setProperty("webdriver.chrome.driver", 
                    "C:\\Users\\Fernanda\\Desktop\\Cursos TI\\ALURA\\Selenium\\chromedriver_win32_v2.25.exe");

//        DesiredCapabilities capabilities = DesiredCapabilities.chrome();
//        WebDriver driver = new ChromeDriver(capabilities);

        WebDriver driver = new FirefoxDriver();

        driver.get("http://www.google.com.br");

        WebElement campoDeTexto = driver.findElement(By.name("q"));
        campoDeTexto.sendKeys("Caelum");

        campoDeTexto.submit();
    }
}

E o erro exibido no console:
