JVM doen't exit in Spring Integrations - spring-integration

Question

I'm new to spring integration and I'm using the following code,
public class Main {
/**
* #param args
*/
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
"trail03ApplicationContext.xml");
MessageChannel channel = applicationContext.getBean(
"helloMessageChannel", MessageChannel.class);
Message<String> message = MessageBuilder.withPayload("World").build();
channel.send(message);
}
}
I don't have any problems in the code but the jvm doesn't exit after sending the message. It still runs in the background. It was evident from the jvmvisual viewer. Is there are anything that needs to shut down. I'm using eclipse for testing the applications.
This is my application Context
