NPE is caused by JCR Session is null when we try to get root node in method DomainSessionImpl#_getRoot(), i guest it's a concurrency issue. This bug is very hard to reproduce. IMO, When user require logout, we should try-cat to ignore all exception when remove cookieToken to be sure that user can logout if he wants. If it's failure to remove this cookieToken we still have other job in background to remove all expired token.
