/**
* While we strongly recommend that users throw {@link ServiceException}s and not {@link WebApplicationException}s,
* these exceptions are part of the JAX-RS standard and a server such as Jersey will throw them even if user code
* doesn't. For instance, {@link ServerRuntime} will throw {@link NotFoundException} if a request couldn't be routed,
* and if we don't handle that in this way, then when using {@link ConjureJerseyFeature} it will get caught by
* {@link RuntimeExceptionMapper} and transformed into a 500 internal exception, which is not what we want.
