Ivan Kelly commented on BOOKKEEPER-175:
---------------------------------------
bq. It was never used.
By which i mean, it was incremented and decremented but the resulting value was
never used.
> Bookie code is very coupled

> Bookie owns EntryLogger, LedgerCache, LedgerDescriptors which all depend on
> each other in strange ways. Sometimes we access the ledgerCache directly,
> sometimes through LedgerDescriptors. etc, etc. It's messy and there's no
> hierarchy.
> I propose that we refactor Bookie to only contain the EntryLogger and
> journalling code (this should be factored at some stage also). The
> EntryLogger can then own the ledgerCache and the LedgerDescriptors, and then
> we would how have to have the entanglement as observed on BOOKKEEPER-160.
