Construct a ServerFailure from a given Throwable. You can then pass specific
"tokens" that your client code will be able to analyze (if needed), but more
importantly, you can tell whether the error should be considered "fatal" or
not (default implementation of onFailure in Receiver throws a
RuntimeException, but only if the ServerFailure is "fatal", which the
DefaultExceptionHandler always produces)

Assuming "requestContext" above actually is a Request (not a
RequestContext), that's abnormal.
If you're indeed talking about a RequestContext (and your T should be read
as Void), then it's the normal behavior: the RequestContext-level Receiver's
onFailure will only be called if the server (more or less) failed to
deserialize the request or serialize the response. When processing service
method invocations, each service method's Receiver's onFailure can be
called, independently of the others, and the RequestContext-level Receiver's
onSuccess will be called in the end.
Have a look at the doFire method in AbstractRequestContext for the exact
details of the client-side processing.

Just so you know: you're not alone!
