title: How to detect breaking changes in WSDL contracts?
body: <p>We would like to have a setup where when deploying our web services to our staging server, we would get notified if there are any breaking changes in the WSDL contracts by comparing them to the WSDL of our production site.</p>
  
  <p>Are there any tools or services that can help doing this? </p>
  
  <p>Tried <a href="http://www.service-repository.com/comparator/compareWSDL">Membrane WSDL comparer</a> but this threw <code>java.lang.StackOverflowError</code> when trying it out :)</p>
