Do we really need ADD_MESSAGE on JournalStorageManager? ADD_MESSAGE are aways done on Journal.appendAddRecord or appendAddRecordTransactional. With that in hand when you have an ADD on the journal it can't be other thing but ADD_MESSAGE. I'm asking that because we are making an extra copy just to place the ADD_MESSAGE byte. We could eliminate it if we didn't need that. I would of course keep the bytes on ACKs and MessageCounter.
