runAs feature doesn't works 
----------------------------

                 Key: SHIRO-344
                 URL: https://issues.apache.org/jira/browse/SHIRO-344
             Project: Shiro
          Issue Type: Bug
          Components: Realms 
    Affects Versions: 1.2.0
            Reporter: yourik
             Fix For: 1.2.1


Right after SecurityUtils.getSubject().runAs(new new SimplePrincipalCollection(){...})

SecurityUtils.getSubject().getPrincipal() returns correct new Principal
SecurityUtils.getSubject()..getPreviousPrincipals() returns correct original Principal

but DefaultSubjectDAO merge principals in method

protected void mergePrincipals(Subject subject) {
  PrincipalCollection currentPrincipals = subject.getPrincipals();
  ...
  if (session == null) {
  ...
  } else {
    PrincipalCollection existingPrincipals = (PrincipalCollection) session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);
    if (CollectionUtils.isEmpty(currentPrincipals)) {
      ...
    } else {
       if (!currentPrincipals.equals(existingPrincipals)) {
            session.setAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY, currentPrincipals);
      }
   }
}


and after that
SecurityUtils.getSubject().getPrincipal() and SecurityUtils.getSubject().getPreviousPrincipals()
both returns new Principal - this is wrong behavior
