Simple bug in the JournalNode: it caches certain values (eg accepted epoch) in memory, and the cached values aren't reset when the journal is formatted. So, after a format, further calls to the same Journal will see the old value for accepted epoch, writer epoch, etc, preventing the journal from being re-used until the JN is restarted.
