* Variation of Jetty's {@link ErrorPageErrorHandler} that supports all {@link HttpMethod
* HttpMethods} rather than just {@code GET}, {@code POST} and {@code HEAD}. By default
* Jetty intentionally only
* supports a limited set of HTTP methods for error pages, however, Spring Boot
* prefers Tomcat, Jetty and Undertow to all behave in the same way.
