UnsupportedCommandException while executing seleium script with firefox 59.0.3 (64-bit) gecko driver 0.15 - selenium-firefoxdriver

Question

I am a beginner in Selenium. This is my code I am executing. I am using Selenium-Java-3.3.1 version, Firefox 59.0.3 (64-bit) and gecko driver 0.15 version
package selenium_test;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
public class TestClass {
WebDriver driver;
public void invokeBrowser() {
try {
System.setProperty("webdriver.gecko.driver", "D:\\GEGDC\\KT00475829\\Downloads\\geckodriver-v0.15.0-win64\\geckodriver.exe");
driver = new FirefoxDriver();
driver.manage().deleteAllCookies();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
driver.get("https://stg2-magic.health.ge.com:13007/enovia/common/emxNavigator.jsp");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String args[]) {
TestClass myObj = new TestClass();
myObj.invokeBrowser();
}
}
Below is my error:
