Rakesh R commented on BOOKKEEPER-847:
-------------------------------------
Its interesting. I couldn't find the possibility of this Exception, as I
remember the re-replication will happen on the closed fragment. Now, it won't
hit the case of updating the ensemble while re-replication of that particular
fragment is in progress, right?. Could you please give more details like,
exception trace or point me to the code flow where it can occur this.

> ArrayIndexOutOfBoundsException in

> might happen after re-read ledger metadata, so the ensemble might already
