title: Bytecode Scanning error on META-INF/versions/9/* and Elasticsearch 6.2.2+ with Jetty 9.2
body: <p>Running GWT app in the Superdev mode with the latest versions of Elasticsearch (above 6.1.1) creates the following error (see below).
  It is clear that the issue has to do with the outdated version of Jetty.
  Does anyone know how to replace Jetty in GWT or change the configuration in IntelliJ to use a different server? The instructions in GWT documentation are, in my opinion, poorly written.  Ideally, of course, I wish there was a way to change Jetty directly in GWT so that all projects can use the updated version instead of configuring each project with its own server. </p>
