> When using a remote WebDriver, trying to take a screenshot as described in [WebDriver documentation|http://seleniumhq.org/docs/04_webdriver_advanced.jsp#taking-a-screenshot]:
> {code:java}
> @Drone
> WebDriver driver;
> ... 
> WebDriver augmentedDriver = new Augmenter().augment(driver);
> byte[] screenshot = ((TakesScreenshot) augmentedDriver).getScreenshotAs(OutputType.BYTES);
> {code}
> results in the following exeception:
> {noformat}
> Caused by: java.lang.ClassFormatError: Duplicate method name&signature in class file org/openqa/selenium/remote/RemoteWebDriver$$EnhancerCGLIB$$58fd8af5$$EnhancerByCGLIB$$558c2b50
> {noformat}
> If the augmentation is omitted, the {{TakesScreenshot}} interface can't be found:
> {noformat}
> java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebDriver$$EnhancerCGLIB$$eda133bb cannot be cast to org.openqa.selenium.TakesScreenshot
> {noformat}
> It seems that the CGLib-enhanced {{RemoteWebDriver}} instance contains the methods of capability providers ({{AddTakesScreenshot}}) but doesn't declare that it implements their corresponding interfaces ({{TakesScreenshot}}).
> Note that taking screenshots works without the augmentation when using a non-remote WebDriver. (When using augmentation it throws the _Duplicate method name&signature_ exception).
