Shiro的SimpleAuthenticationInfo的principal赋值问题

Question

doGetAuthenticationInfo 在 return 时 SimpleAuthenticationInfo 的赋值

 return new SimpleAuthenticationInfo(user.getStr("username"), user.getStr("password"), getName());

验证可以通过，当改为

 return new SimpleAuthenticationInfo(new ShiroUser(user), user.getStr("password"), getName());

抛出异常

Possible unexpected error? (Typical or expected login exceptions should extend from AuthenticationException).

不知是哪里错了。
