Shutting down Apache ActiveMQ

Question

I'm running a Spring Boot (1.3.5) console application with an embedded ActiveMQ server (5.10.0), which works just fine for receiving messages. However, I'm having trouble shutting down the application without exceptions.

This exception is thrown once for each queue, after hitting Ctrl-C:

2016-09-21 15:46:36.561 ERROR 18275 --- [update]] o.apache.activemq.broker.BrokerService   : Failed to start Apache ActiveMQ ([my-mq-server, null], {})

It seems as the DefaultMessageListenerContainer tries to start an ActiveMQ server which doesn't make sense to me. I've set the phase of the BrokerService to Integer.MAX_INT - 1 and the phase of DefaultJmsListeningContainerFactory to Integer.MAX_INT to make it go away before the ActiveMQ server is stopped.

I have this in my main():

public static void main(String[] args) {
    final ConfigurableApplicationContext context = SpringApplication.run(SiteServer.class, args);
    context.registerShutdownHook();
}

I've tried setting daemon to true as suggested here: Properly Shutting Down ActiveMQ and Spring DefaultMessageListenerContainer .

Any ideas? Thanks! =)

Found it. This problem occurs when the Camel context is shutdown after the BrokerService. Adding proper life cycle management so that Camel is shutdown before resolved the issue. Now everything is shutdown in a clean way without errors.
