Fixes JIRA issue SGF-198 involving a BeanCurrentlyInCreationException when an AsyncEventListener is defined for any AsyncEventQueue and Spring Data GemFire injects the listener into the constructor of the AsyncEventQueueFactoryBean and the AsyncEventListener is using constructor injection to some other arbitrary bean dependency in the Spring application context.
