У нас есть приложение Java, которое загружается с помощью Spring WebApplicationInitializer на Jetty 9.2:

Однако, если мы обновимся до Jetty 9.4, WebApplicationInitializer не будет поднят, и каждая страница получит 404 (хотя статические ресурсы все еще видны):

Существует ли какой-либо конкретный модуль Jetty, который нам нужно включить для получения ServletContainerInitializer экземпляров? У меня сложилось впечатление, что ServletContainerInitializer является довольно стандартным начиная с Servlet 3.0, а Jetty 9.4 использует 3.1. Или, может быть, нужно что-то еще, чтобы инициализатор контейнера Spring обнаружил наш WebApplicationInitializer?
Jetty 9.4 сообщает следующее:

И наше приложение разворачивается с использованием файла контекста Jetty:
