Ability to use variable substitution in Vert.X config is unpredictable

      Depending on a how the specific section of configuration file is parsed variable substitution may or may not work.

      For some sections (my guess is everything not related to vertx) all configuration values are treated as Strings. Here the substitution works fine, e.g.

      "metrics": {
    "class": "io.apiman.gateway.engine.es.ESMetrics",
    "config": {
      "client": {
        // omitted
        "port": "${es.port}",
      }
    }
  },

      However VertX related configuration is "Typed" and thus the substitution doesn't work, e.g. 

      "http": {
    "port": "${apiman.verticles.http.count}",
    "count": "auto"
},

      Related java snippet from VertxEngineConfig.java

          public JsonObject getVerticleConfig(String verticleType) {
        return config.getJsonObject(VERTICLES).getJsonObject(verticleType.toLowerCase());
    }

      After this, the following error message should not be a surprise

      java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Number
