--------------------------------------
I have spoken too soon. Actually, the session is being created but the consumer
cannot receive any message. Its call to receive is timeouting. In the below
code, the 2nd test is failing
Successful test Log:

> As discussed in this

> if the links provided in the failover URL are ordered in a way to have the
> Replicate first and then the Master. Then the connection will fail and an
> error will be thrown client-side.
> This is because the multi-threading behavior in the FailoverProvider is not
> correct. The main thread will not wait for the connection trial thread to try
> and find the active Master node. If we add a Sleep or debug the main thread
> to give the connection trial thread enough time to find the Master URL then
> the test works
