I am trying to do a Buddy Replication.
I have three nodes cluster
Node 1 Node 2 node 3
My application works fine.
But when I stop node1 and continue using the application, but as soon as I click to add some
values to some cached object (my application is a Shopping cart app and stores some
values in session). I get a null pointer exception. Note sure why.
As soon I get NullPointerException,
Node 2 console shows the following message :-
14:43:37,823 INFO [DLQ] Bound to JNDI name: queue/DLQ
14:44:05,667 INFO [CacheListener] Possible concurrency problem: Replicated version id 1 matches in-memory version for session d

And Node 3 shows:-
