[jboss-dev-forums] [Design of Clustering on JBoss] - JBAS-5703 - Make HA-JNDI use wait for first positive respons

Re: https://jira.jboss.org/jira/browse/JBAS-5703

I've attached a patch containing fix for this. Few notes:

1. I've tested this with a 3 node cluster (node1,node2 and node3) and two ejbs (ejbA and ejbB where ejbA calls ejbB via HAJNDI). Deployment wise, ejbA is deployed in node1 and ejbB is deployed in node3. I was able to make a call successfully via ejbA in node1 and was able to check via logs that once response from node3 was received, the lookup returned. Now, my question is, how to create a unit test around this? Not easy...

2. I noted this as a todo in the patch: ResponseFilter/RspFilter API: If needMoreResponses() took response and sender as well, class implementations could be Immutable and same instance could be passed to all lookups. As it is right now, they can't and new instances need to be generated for every lookup.

3. Could response filtering done in ClusterPartition.processResponseList() be moved here? Any NoHandlerForRPC would be caught here immediately and could potentially avoid double processing. Thoughts?
