GAE 中的 Google Pub/Sub

Question

在 GAE 应用程序中使用 pub/sub java 客户端库不起作用，我得到一个异常

Caused by: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "shutdownHooks")

基本上它试图添加一个不允许的关闭挂钩。

我错过了什么？

该库暂不支持GAE标准环境，只支持灵活，见https://github.com/GoogleCloudPlatform/google-cloud-java/tree/master/google-cloud-pubsub

这应该记录在 Google 文档中，而不是 Github 中的说明
