> Every MailboxSession has an id which is in fact a long. The Id should be unique during until the jvm was restarted (or at least unique enough that active mailboxsessions don't have the same id). We generate this id by using Random.nextLong() which fullfill our needs. The only problem is that Random.nextLong() may return 0L if we are lucky enough. This is a problem as we use 0L as id for MailboxSessions which where create by the "system". So 0L serve a special purpose. 
> So we need to make sure that 0L will never get returned for a generated MailboxSession id.
