java.security.AccessControlException：拒绝访问（“java.lang.RuntimePermission”“modifyThreadGroup”）

标签： java hibernate google-app-engine

我正在创建一个使用Google App Engine，Java，Hibernate和Google SQL的Web应用程序。出于开发目的，我将项目配置为使用MySQL。当我尝试使用hibernate构建Session时，我最终得到了这个异常。 

Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        
sessionFactory = configuration.buildSessionFactory(serviceRegistry);

异常消息如下。我正在使用基于XML的映射。

我在war / WEB-INF / lib中添加了所有库。

虽然这似乎与this非常相似。那里没有答案，所以我正在创建这个帖子。
