http://jira.hyperic.com/browse/HHQ-4078
If the Guest User has been deleted HQ becomes inoperable. This is a regression caused by the addition of the LoginController in 4.3.
It attempts to load the guest user using a find():
LoginController:57
AuthzSubject guestUser = authzManager.findSubjectById(AuthzConstants.guestId);
This should instead use getSubjectById(AuthzContants.guestId) so that null is returned instead of a lazy loaded proxy.
