This interface will be implemented by those components wishing to
be notified when requests are received on the server-side and when
responses have been constructed on the server-side. Implementations
can be registered with the FactoryRegistry.
This method will be called anytime that an exception occurs
within the JAX-WS server-side code flow. InvocationListener
instances may change the exception being operated on by setting
property on either the request or response MessageContext. The
value of the property should be an instance of Throwable.
