Project: Shiro
Issue Type: Bug
Affects Versions: 1.2.0

When the following method is called:
public Subject getSubjectByLogin(final String login) {
PrincipalCollection principals = new
SimplePrincipalCollection(login, REALM_NAME);
return new
Subject.Builder().principals(principals).buildSubject();
}
it throws an exception on buildSubject():

It tries to create a session but really should not.
