webdriver find element css selector cannot cope with complex search, An invalid or illegal string was specified

I am having difficulty with the Webdriver .findElement() method, here is the code in question:

driver.findElement(By.cssSelector("div[id='container1'] > div + div > div)")).click();

When I use the the same CSS selector using CTRL + ALT + S selenium firefox add-on, it works fine but not using Webdriver, why?

Here is the stack trace:

You have an extra closing bracket at the end of the css-selector (right before the closing quotation).

Try:

driver.findElement(By.cssSelector("div[id='container1'] > div + div > div")).click();
