bean definition profiles, and application context initializers.

Any ApplicationContext loaded by a ContextLoader must register a JVM shutdown hook for itself. Unless the context gets closed early, all context instances will be automatically closed on JVM shutdown. This allows for freeing external resources held by beans within the context, e.g. temporary files.
