I just got around to integrating php web-driver with my current project, but I've seemed to have run into an issue.

  $web_driver = new WebDriver( 'http://192.168.1.251:4444/wd/hub' ); // could pass a host besides localhost

  $session = $web_driver->session(); // could pass a browser name

  $session->open('http://www.google.com');
  $session->close();

My Selenium Server is generating output of
WebDriver remote server: Fatal, unhandled exception: /session/1321907086012: java.util.concurrent.ExecutionException: java.lang.NullPointerException

Is there a way to stop that exception from outputting?
