no send puback

[vivainyan]

use CallbackConnection,When i receive a lot of publish package, it will no longer send ack package； this is my code segment: listener = new ExtendedListener() { @Override public void onPublish(UTF8Buffer topic, Buffer body, Callback<Callback> ack) { ack.onSuccess(new Callback() { @Override public void onSuccess(Void value) { logger.info("SEND PUBACK SUCCESSED!"); }

                @Override
                public void onFailure(Throwable value) {
                    logger.error("SEND PUBACK FAIL！");
                }
            });

}
