> We had an internal discussion about this. From BOOKKEEPER-337, it seems that
> handleBookieFailure could be invoked in parallel by a thread other the one
> that calls LedgerHandle#sendAddSuccessCallbacks. The values updated by
> handleBookieFailure might not be visible to the thread running
> sendAddSuccessCallbacks because the fields are not volatile and this might
> have caused our bad state.
> BK-337 synchronizes access to metadata.addEnsemble() and we believe this
> would make this scenario very improbable.
> A long term fix might be to make LedgerMetadata immutable since it is rarely
> updated.
