在 App Engine 上使用 Spring AOP 会导致 StackOverflowError

我们有一个在 App Engine 上运行并使用 Spring 框架的应用程序。最近我们添加了一些基于AOP的新功能。我们决定使用 @AspectJ 风格，因此我们添加了<aop:aspectj-autoproxy>进入我们基于 XML 的配置并实现各个方面。在开发服务器上一切正常，但是，当部署到云环境时，我们得到java.lang.StackOverflowError每次应用程序初始化时。

无法创建并导致错误的bean是注释为的配置类@Configuration注解。看起来基本上任何配置 bean 都可能导致错误。

下面您可以看到相应的堆栈跟踪。
