AbstractRestHandler
CompletableFuture
containing a the response.
Implementations may decide whether to throw RestHandlerException
s or fail the
returned CompletableFuture
with a RestHandlerException
.
Failing the future with another exception type or throwing unchecked exceptions is
regarded as an implementation error as it does not allow us to provide a meaningful HTTP
status code. In this case a HttpResponseStatus.INTERNAL_SERVER_ERROR
will be
returned.
