public class PreferredMediaTypeHttpErrorHandler
An `HttpErrorHandler` that delegates to one of several `HttpErrorHandlers` depending on the client's media type
preference. The order of preference is defined by the client's `Accept` header. The handlers are specified as a
`LinkedHashMap`, and the ordering of the map determines the order in which media types are chosen when they are
equally preferred by a specific media range (e.g. `*\/*`).
