Session Failover with Sun GlassFish(tm) Message Queue 4.4 - Part II

Now, what if the pair of OpenAM servers are running and suddenly the Message Broker has stopped abruptly?

Firstly, nothing will happen. Not until the next person tries to access either of the OpenAM.


Then you should be able to see the following exception stack trace in Session debug log:
