Laurent Bigonville updated ARTEMIS-1733:
----------------------------------------
    Description: 
Hi,

When using the client-side-load-balancing from apache activemq artemis examples 
on my own setup (2 RH amq) I see that the first connection is always going to 
the same broker. The documentation says that 
RoundRobinConnectionLoadBalancingPolicy should 1st pick up a random broker and 
then do round-robin, but that 1st step doesn't seems to work.

I've the the following string in the jndi.properties and starting the example 
with mvn -PnoServer verify:

{{java.naming.factory.initial=org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory}}
{{ 
connectionFactory.ConnectionFactory=tcp://foo.example.com?user=user;password=password}}
{{ queue.queue/exampleQueue=exampleQueue}}

Adding some printnl() in the select() function of 
RoundRobinConnectionLoadBalancingPolicy, I see that pos = 
RandomUtil.randomInterval(0, max); is being called with max value of 1 the 1st 
time(should be 2 as there are two servers). The subsequent calls to that 
functions show that max value is then set to 2 as expected.

This explains why I always get my applications to connect to the same broker.
