Description
We should mark MessageManager.isWriteable(MailboxSession session), MessageManager.isModSeqPermanent(MailboxSession session) and MessageManager.getMessageCount(MailboxSession mailboxSession) as @Deprecated. These infos should get accessed via the MessageManager.getMetaData(boolean resetRecent, MailboxSession mailboxSession, MessageManager.MetaData.FetchGroup fetchGroup) method.
