A Groovy Elasticsearch scriptlet that will not join a cluster because of the resolver strategy in GXContextBuilder

  // Warning **This does not do what you want it to**. Because the scriptlet appears to implement 
  // the setProperty method, the setters here will be called against the DemoContextProblem class and not
  // the nodeBuilder as you want. Thus, this class can never join the cluster as it
  // never receives any config properties. Although everything looks normal, 
  // you will always see "ping response {none}" in the logs if you're running a non-default cluster name.
