code: public static Map jsonToMaps(InputStream inputStream, Map<String, Object> optionalArgs)
      {
          if (optionalArgs == null)
          {
              optionalArgs = new HashMap<String, Object>();
          }
          optionalArgs.put(USE_MAPS, true);
          JsonReader jr = new JsonReader(inputStream, optionalArgs);
          Object ret = jr.readObject();
          jr.close();
  
          return adjustOutputMap(ret);
      }
docs: Map args = ["USE_MAPS": true]
  Use JsonReader.jsonToJava(inputStream, args)
  Note that the return type will match the JSON type (array, object, string, long, boolean, or null).
  No longer recommended: Use jsonToJava with USE_MAPS:true
  @param inputStream containing JSON content
  @param optionalArgs Map of optional arguments to control customization.  See readme file for
  details on these options.
  @return Map containing the content from the JSON input.  Each Map represents an object from the input.
