使用 Shiro 注销时出现 IllegalStateException

Question

我正在使用 Shiro 进行身份验证的 glassfish 4.0 上的 ZK 7.0.2 项目。用户使用以下代码登录：

Subject currentUser = SecurityUtils.getSubject();
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
token.setRememberMe(false);
currentUser.login(token);
Executions.sendRedirect(HOME_URL);

注销是通过以下方式完成的：

Subject subject = SecurityUtils.getSubject();
subject.logout();
Executions.getCurrent().sendRedirect("/login.zul");

登录时，我遇到了几个空指针异常，但经过几次尝试后它登录了。堆栈跟踪如下所示：

注销时，我得到类似的行为。注销时遇到的stacktrace如下所示。

Delegate RememberMeManager instance of type [org.apache.shiro.web.mgt.CookieRememberMeManager] threw an exception during onSuccessfulLogin.  RememberMe services will not be performed for account [admin].

我尝试了各种技巧，但都没有成功。任何帮助都感激不尽。谢谢。

原来这个错误是由添加引起的

<disable-event-thread>false</disable-event-thread>

到 zk.xml 文件。
