code: JsTopicMessageController getJsTopicMessageControllerFromJsTopicControls(String topic) {
  		logger.debug("Looking for messageController for topic '{}' from JsTopicControls annotation", topic);
  		Instance<JsTopicMessageController<?>> select = topicMessageController.select(new JsTopicCtrlsAnnotationLiteral());

docs: without jdk8, @Repeatable doesn't work, so we use @JsTopicControls annotation and parse it
  @param topic
  @return
