Will queueInfo.getTotalMessage appear to be -1?

[Yuan-zs]

Hi,
I noticed that the property totalMessage of (com.rabbitmq.http.client.domain)QueueInfo is assigned a value of -1 in the constructor. Are there some rare cases such as server problems or other issues that cause
QueueInfo queueInfo = client.getQueue("xx","xx");
queueInfo.getTotalMessage() == -1 //true?
Thank you.

If the value was never set, for example, because the metric was not computed at the moment you have requested it, it can be set to something like -1 by the JSON (de)serializer.

RabbitMQ itself may return a value like this for some metrics but IIRC the total counts is not one of them.

Thanks for the reply.
