Cant start opera in grid configuration

[kronar]

Steps. to reproduce:

1. start selenium grid hub on localhost (java -jar selenium-server-standalone_.jar -role hub)
2. start node on the same host (java -jar selenium-server-standalone_.jar -role node -hub http://localhost:4444/grid/register -port 9000 )
3. Try to execute following code

import java.net.MalformedURLException; import java.net.URL;

import org.junit.Before; import org.junit.Test; import org.openqa.selenium.WebDriver; import org.openqa.selenium.remote.DesiredCapabilities; import org.openqa.selenium.remote.RemoteWebDriver;

public class TestOpera {

private WebDriver driver;

@Test
public void testOperaOnGridConfiguration() throws MalformedURLException{
    driver.get("http://opera.com");

}

@Before
public void initDriver() throws MalformedURLException {
    driver = new RemoteWebDriver(new URL("http://127.0.0.1:4444/wd/hub"), DesiredCapabilities.opera());
}

}

The exceprion is following

org.openqa.selenium.WebDriverException: Error forwarding the new session cannot find : {platform=ANY, browserName=opera, version=} Command duration or timeout: 151 milliseconds Build info: version:

Is there any specific settings for starting Opera in selenium grid configuration ?
