Description

I recently upgraded to NMS ActiveMQ 1.5.2 and when I restart the broker, the connection and the consumers get restored, but they get restored to the "pull" mode, which means the broker will not send them messages automatically. This isn't how the previous version behaved. What I need is for it to recover back to the way it was, which was prefetch 1000. I think I must be missing a setting for the failover URL or something like that.

My URL looks like this:

failover:(tcp://localhost:61616?consumer.prefetchSize=1266)

I peaked at the source and it looks like the final "completion" isn't getting to this area:

Tracer.Debug("restored recovering consumer: " + control.ConsumerId + " with: " + control.Prefetch);

Here is the log output from the consumer.
