Shiro Realm and Session tread-safety?

[Alex Orlov]

Hi all,
 
As I understand Shiro must be thread-safe. However, I couldn’t find any 
information about
multithreading support, so, to be sure decided to ask several questions. Could 
anyone say, if
 
1) this code with sessions is thread-safe?
    for (Session session: sessionDao.getActiveSessions()){
           …..
            session.stop();
    }
 
2) Real#clearCachedAuthorizationInfo(PrincipalCollection principals) method is 
thread-safe?
