> the LedgerDescriptor will be created when it is missed in LedgerCache.
> NullPointException will be thrown out in the following case:
> 1. The ledger descriptor is created and cached to LedgerCache because of a
> readEntry operation in bookie. The ledger descriptor was created without
> setting master key (we don't know master key in a read request)
> 2. An addEntry is sent after 1 . since the ledger descriptor has been cached,
> so addEntry will use it to compare master key. then NullPointException is
> thrown out.
