After sending a message(s), some properties have bad values:

Count = 0,
Count Delta = 0,
Time Last Update = 0,

However,

Depth 4 The current message count of pending messages within the queue waiting for dispatch
Depth Delta 3 The message count delta of pending messages since last method call

Did the meaning of Count change?

I've looked at the queue MBean in JMX console, and there's no count property. Jopr takes this from ProfilseService, so perhaps that's where zero comes from? Anyway, this is a regression.
