Sijie Guo commented on BOOKKEEPER-847:
--------------------------------------
[~rakeshr] I just took at the code
{code}
int deadBookieIndex = ensemble.indexOf(oldBookie);
ensemble.remove(deadBookieIndex);
ensemble.add(deadBookieIndex, newBookie);
{code}
this is definitely a bug. indexOf would return -1 (
http://docs.oracle.com/javase/7/docs/api/java/util/List.html#indexOf(java.lang.Object)
)

> ArrayIndexOutOfBoundsException in
> LedgerFragmentReplicator::updateEnsembleInfo, because update ensemble info
> might happen after re-read ledger metadata, so the ensemble might already
> change. if ensemble is already changed, skip replacing the bookie doesn't
> exist.
