/**
 * This is @Component to give spring a hint in configuration ordering. 
 * If using this class might cause issues when using with tests. In test, spring can re-initialise the ApplicationContext and invalidates the old one. 
 * Although this class uses application listeners to be notified about the new ApplicationContext, it doesn't work reliably. Tests needs to make sure to set the new 
 * ApplicationContext to this class. The simplest way to do this is to extend the test class from BaseIntegrationTest.
