当会话超时时，我的 @SessionScoped WorkflowManager 托管 bean 能够重置状态，从而导致显示欢迎启动屏幕。将@Stateful 添加到 WorkflowManager 后，欢迎屏幕并没有始终如一地显示，而且从查看 server.log 来看，会话实际上并没有以一致的方式正确超时。当浏览器在会话超时后发出请求时， ViewExpiredExceptionHandler 应该重定向到启动屏幕。相反，出现的是以下堆栈跟踪和警告：

会话超时后，应销毁 WorkflowManager，并且来自客户端的下一个请求应导致创建新的 WorkflowManager。当 WorkflowManager 是托管 bean 时，这就是它工作得很好的方式。那么，为什么 JBoss 会尝试恢复之前被破坏的 WorkflowManager？我能做些什么来解决这个问题？
