Retained Flag in MQTT

Hi,
I'm having trouble with the retained flag on mqtt. Setting retained puts a
default post into a topic, so any new subscribers get that message first.
Doesn't seem to work though. I'm using latest paho client and activemq
version 5.9 SNAPSHOT with basic matt transport config. Anyone come across
this issue?

Rgds,

Sadly, no. I had to use mosquitto instead.

And on the other side, it is working perfectly with Apollo. 
Is there any major difference in Apollo and Activemq MQTT distribution ?

Hi Christian,

I am using apache-activemq-5.9-20130919.101342-100.

i tried retained message with two different clients, it is showing same
problem.
Clients get connected to MQTT flawlessly and can publish and subscribe to
topics but the messages flagged as retained are not coming whenever new
consumer is attached.

Thanks
