title: Issue launching Phantomjs Selenium Web Driver
body: <p>I'm using phantom.js driver for selenium in some java code.
  It's a large project so i'll only copy what I think is the relevant code.</p>
  
  <p>I had it working fine with the firefox driver.</p>
  
  <p>I instantiate it here: </p>
  
  <pre><code>     Capabilities caps = new DesiredCapabilities();
                  ((DesiredCapabilities) caps).setJavascriptEnabled(true);
                  ((DesiredCapabilities) caps).setCapability("takesScreenshot", true);
                  ((DesiredCapabilities) caps).setCapability("timeoutInSeconds", 20);
                  ((DesiredCapabilities) caps).setCapability(
                          PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
                          "/Applications/phantomjs-2.0.0-macosx/bin/phantomjs"
                  );
                  WebDriver driver = new PhantomJSDriver(caps);
  
  driver.get(base_url+searchQuery.urlString());
  </code></pre>
  
  <p>Then when I run the program I get a list of errors:</p>
  
  <pre><code>    SEVERE: org.apache.commons.exec.ExecuteException: Process exited with an error: 137 (Exit value: 137)
  Exception in thread "main" org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
