Buggy source:
@Override public void notifyPublishPost(final HttpServerRequest request,final String blogId,final String postId,final UserInfos user,final String resourceUri){
  if (resourceUri != null && user != null && blogId != null && request != null) {
    QueryBuilder query=QueryBuilder.start("String_Node_Str").is(postId);
    JsonObject keys=new JsonObject().putNumber("String_Node_Str",1).putNumber("String_Node_Str",1);
    JsonArray fetch=new JsonArray().addString("String_Node_Str");
    findRecipiants("String_Node_Str",query,keys,fetch,user,new Handler<Map<String,Object>>(){
      @Override public void handle(      Map<String,Object> event){
        if (event != null) {
          List<String> recipients=(List<String>)event.get("String_Node_Str");
          JsonObject blog=(JsonObject)event.get("String_Node_Str");
          if (recipients != null) {
            JsonObject p=new JsonObject().putString("String_Node_Str",container.config().getString("String_Node_Str") + "String_Node_Str" + user.getUserId()+ "String_Node_Str"+ user.getType()).putString("String_Node_Str",user.getUsername()).putString("String_Node_Str",blog.getObject("String_Node_Str",new JsonObject()).getString("String_Node_Str")).putString("String_Node_Str",resourceUri).putString("String_Node_Str",blog.getString("String_Node_Str")).putString("String_Node_Str",resourceUri + "String_Node_Str" + postId);
            try {
              notification.notifyTimeline(request,user,NOTIFICATION_TYPE,NOTIFICATION_TYPE + "String_Node_Str",recipients,blogId,postId,"String_Node_Str",p);
            }
 catch (            IOException e) {
              log.error("String_Node_Str",e);
            }
          }
        }
      }
    }

  }
}

Fixed version (ground truth):
@Override public void notifyPublishPost(final HttpServerRequest request,final String blogId,final String postId,final UserInfos user,final String resourceUri){
  if (resourceUri != null && user != null && blogId != null && request != null) {
    QueryBuilder query=QueryBuilder.start("String_Node_Str").is(postId);
    JsonObject keys=new JsonObject().putNumber("String_Node_Str",1).putNumber("String_Node_Str",1);
    JsonArray fetch=new JsonArray().addString("String_Node_Str");
    findRecipiants("String_Node_Str",query,keys,fetch,user,new Handler<Map<String,Object>>(){
      @Override public void handle(      Map<String,Object> event){
        if (event != null) {
          List<String> recipients=(List<String>)event.get("String_Node_Str");
          JsonObject blog=(JsonObject)event.get("String_Node_Str");
          if (recipients != null) {
            JsonObject p=new JsonObject().putString("String_Node_Str",container.config().getString("String_Node_Str") + "String_Node_Str" + user.getUserId()+ "String_Node_Str"+ user.getType()).putString("String_Node_Str",user.getUsername()).putString("String_Node_Str",blog.getObject("String_Node_Str",new JsonObject()).getString("String_Node_Str")).putString("String_Node_Str",resourceUri).putString("String_Node_Str",blog.getString("String_Node_Str")).putString("String_Node_Str",resourceUri + "String_Node_Str" + postId);
            notification.notifyTimeline(request,user,NOTIFICATION_TYPE,NOTIFICATION_TYPE + "String_Node_Str",recipients,blogId,postId,"String_Node_Str",p);
          }
        }
      }
    }
