Фреймворк Spring с Java 8 на Google App Engine не запускается

У меня есть веб-приложение, работающее на Google App Engine (GAE) с использованием Java 7.

Я хочу перейти на Java 8, потому что Java 7 устарела.

Обновлена ​​версия Spring framework до (5.0.6), а безопасность - до (5.0.5).

Я получаю это исключение при запуске:

1. Фреймворк Spring с Java 8 несовместим с GAE?
2. Стоит ли мне переходить на Spring boot?
