title: Selenium method works only in debug mode
body: <p>I've come up against a weird problem! I am a noobie Selenium Framework user, but anyway I use:</p>
  
  <pre><code>wait.until(ExpectedConditions.invisibilityOfElementLocated(xpath)). 
  </code></pre>
  
  <p>This construction works in debug mode only, however, when I run test without debug, it seems like Compiler doesn't check this line. </p>
