    Description

      ScriptBasedClusterAction is using NPE for flow control.

      public Cluster execute(ClusterSpec clusterSpec, Cluster cluster) throws IOException, InterruptedException {
      ...
      for (String role : instanceTemplate.getRoles()) {
      try

      { handlerMap.get(role).beforeAction(event); }

      catch (NullPointerException e)

      { throw new IllegalArgumentException("No handler for role " + role); }

      }
      ...
      }

      I just lost about an hour trying to find out why the actionhandler was not being registered while the NPE came from the beforeAction() call.
