[Sakai Jira] Created: (KERN-1193) Exceptions seen at shutdown
Oszkar Nagy (JIRA)
---------------------------
Key: KERN-1193
URL: http://jira.sakaiproject.org/browse/KERN-1193
Project: Nakamura
Issue Type: Bug
Components: System - other
Affects Versions: 0.8
Reporter: Oszkar Nagy
Priority: Minor
This might be expected/non-issue, if that's the case please disregard - it does not affect normal usage as far as I can see, but maybe it is a pointer to another problem.
When I am shutting down Nakamura in the OSX Terminal window by pressing Ctrl-C *sometimes* it shuts down without any exceptions, sometimes it shuts down with the following exceptions in the logs:

---------------------------------
Exception in thread "ActiveMQ ShutdownHook" java.lang.NoClassDefFoundError: org/apache/activemq/broker/BrokerService$3$1
So some clean up cannot happen because a class is missing?

Ian Boston commented on KERN-1193:
----------------------------------
These are harmless.
The Zip failures are due to new Jars being loaded by the OSGi Container on shutdown, which is triggered by the Shutdown process surrounding ActiveMQ. Since ActiveMQ has already throttled down at this point.
If we had more time we could look into the shutdown procedure for AMQ and unbind it from a JVM triggered shutdown into a OSGi triggered shutdown, which should be possible.
Scheduling for Q2

Ian Boston resolved KERN-1193.
------------------------------
Resolution: Won't Fix
Wont fix, cant fix without a lot of work on the OSGi lifecycle deep within felix.
