Version-Release number of selected component (if applicable):
JON build #166 - Revision:  10620

How reproducible:

Steps to Reproduce:
1) Install JON 2.3 with Postgres 8.4
2) Install one more JON 2.3 server with same database  (High Availability)
3) Install/configure 3 rhq-agests
4) Perform operations on JON 2.3
 (i) Create alerts for platform, JBoss AS4, RHQ Agent, Compatible group (alert
condition is Free Memory > 0.1 OR Total Memory < 999999)
 (ii) Create groups (Mix, Compatible, Group defination)
 (iii)Content repository syncronization (for JBoss Patch)
 (iv) Create Roles and Users
 (v) Change INVENTORY -> CONNECTION of JBoss AS4 
 (vi)Change configuration values of 'RHQ Agent' and create 'History'
 (vii)Perform LDAP settings
 (viii)Create 'SCHEDULES' for 'View Process List' on platform
5) Upgrade JON 2.3 to JON 2.4 (JON build #166) - Complete installation process
6) Log-in JON 2.4 (JON build #166)
7) Check server log for any database error/exception
Actual results:
Upgrade JON 2.3 to JON 2.4 with Postgres 8.4 gives error/exception
(UndeclaredThrowableException) in server log file.

Expected results:
Upgrade JON 2.3 to JON 2.4 should upgrade with all its data without any

Please refer attached server log.

Comment 1 Heiko W. Rupp 2010-05-25 15:36:12 UTC
did you stop the agents before step 5?

Comment 2 Heiko W. Rupp 2010-05-25 15:41:40 UTC
See my previous comment - it looks like the agents try to talk to the server "too early" the error messages
vanish as soon as this line is reached:

2010-05-25 16:25:57,714 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/]] initializer: Starting the server-agent communications services

(10:42:04 AM) pilhuhn: ccrouch: https://bugzilla.redhat.com/show_bug.cgi?id=595727 looks like a pilot error
(10:43:15 AM) ccrouch: pilhuhn: ok great, though i think there is still a bug here right?
(10:43:40 AM) ccrouch: i.e. we shouldn't let the agents connect until we're ready to receive them
(10:44:26 AM) pilhuhn: one could perhaps start the agent-comm service somewhat earlier. The underlying issue is that Tomcat sees the foo.war and directly offers this as available to clients
(10:44:40 AM) ccrouch: with agent autoupgrade there is no requirement to shutdown all agents prior to upgrading the server right?
(10:44:47 AM) pilhuhn: and tomcat is starteed very early
(10:44:58 AM) ccrouch: right, so that is something we could look at addressing in the future
(10:47:38 AM) pilhuhn: I don't think that you need to shut them down.Actually one of the agents connects initially as 1.3.0 and later re-connects as 3.0.0 version
(10:48:04 AM) pilhuhn: So yes there is room for future improvement, ccrouch 
(10:48:33 AM) ccrouch: ok, i think this is acceptable for right now
(10:48:40 AM) ccrouch: i'll lower the priority
(10:49:06 AM) pilhuhn: I'll write a FR
(10:50:18 AM) ccrouch: pilhuhn: ok great, can you close this one out and link it to your new one

Comment 4 Charles Crouch 2010-05-25 16:10:12 UTC
We've added  https://bugzilla.redhat.com/show_bug.cgi?id=595792 for a feature request to try to prevent these messages in the future.
