我使用Spring MVC（不是Spring Boot）作为基于Google App Engine REST的Web应用程序。今天，我将GAE Java运行时升级到1.8（Java 8）和servlet-api 3.1。应用引擎开发工具包版本 1.9.56。
所有春豆都能完美加载，没有任何错误。我在提供请求时收到此异常：

这是我的应用程序引擎网络.xml：
<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
<!-- Test GAE instance -->
<application>webapp-1013</application>

<runtime>java8</runtime>
<system-properties>

</system-properties>
<sessions-enabled>true</sessions-enabled>
<inbound-services>
<service>warmup</service>
</inbound-services>
</appengine-web-app>
当我在 GAE 中使用 Java 7 运行时时，我没有遇到这个问题。请帮忙。
您似乎遇到了一个影响 Windows 上开发应用服务器的错误（它不会影响部署到生产 App Engine 的应用）。 该错误正在跟踪：https://issuetracker.google.com/issues/63595917
即将发布的 SDK 版本 1.9.58 中包含对此的修复。
