Subject Re: When will activemq-core 5.9 be present in maven central repo?
Date Thu, 05 Dec 2013 20:39:58 GMT
It's hard to create an isolated test app, found it hard where to start (a
client app that is bit large).
But I did some more digging and found the following:

In the unit tests I create a global Spring ApplicationContext and call the
method ctx.registerShutdownHook() on the context such that all beans are
informed when the jvm is shutdown (Spring uses a separate Thread to monitor
the JVM shutdown.

I removed the error when I don't call "ctx.registerShutdownHook()" and added
"useShutdownHook="false"" to the broker spring config (see:  LINKE
<http://stackoverflow.com/questions/9591203/unable-to-shutdown-embedded-activemq-service-using-the-built-in-brokerservice-st>

).

Notes:
1) Other combinations of these settings result in the exception.
2) I am not sure this is correct as currently my beans aren't informed of
the jvm shutdown such that they can't do any clean up.
3) If I enable the shutdown hook on the Spring context it will kind of end
up in the same exception but through a different path. Spring will call the
destory method on the XBeanBrokerService bean, the broker will perform a
async stop and try shutdown all TransportConnection instances, see
screenshots. <http://activemq.2283324.n4.nabble.com/file/n4675222/1.png> 
<http://activemq.2283324.n4.nabble.com/file/n4675222/2.png> 

4) If I enable the shutdown hook on the broker, I end like shown in the
screenshots. Also an async stop is performed but called through the brokers
own hook (a hook in the XBeanBrokerService).

I can't really discover something strange as a exception is thrown to inform
others (as far as I understand it).
I hope this helps to solve it. 
More info, let me know?
