public @interface CallbackHandler
```
Used to mark a bean as a handler for stateless async callback replies. A bean annotated with this qualifier must implement exactly one stateless async callback interface (which extends StatelessAsyncCallback). When using callback handlers, the application should use the ServiceLocator during Startup to obtain a proxy instance for which the annotated callback should be used, in order for the system to be able to register the callback for use with that proxy.
