All Implemented Interfaces:

EventListener, FacesListener, SystemEventListener, FacesWrapper<ExceptionHandler>
```
public abstract class ExceptionHandlerWrapper
extends ExceptionHandler
implements FacesWrapper<ExceptionHandler>
```
Provides a simple implementation of ExceptionHandler that can be subclassed by developers wishing to provide specialized behavior to an existing ExceptionHandler instance. The default implementation of all methods is to call through to the wrapped ExceptionHandler instance.

Usage: extend this class and override getWrapped() to return the instance we are wrapping.
