If you throw exceptions in the code below instead, you can have a more
specialized return type here, which I slightly prefer.
Not all errors currently have exceptions (e.g. 503 is missing), but it's
easy to add them.
(I also don't remember exactly what version of JAX-RS is being used by
Spark, but if it's 2.1, that version has all these exceptions already, so some
cleanup could be done here. 2.0 doesn't have them though.)
