Block reply = r.datanode.updateReplicaUnderRecovery(
r.rInfo, recoveryId, newBlock.getNumBytes());
assert reply.equals(newBlock) &&
reply.getNumBytes() == newBlock.getNumBytes() :
"Updated replica must be the same as the new block."; <----- line

{noformat}
Not sure how reply could be null since updateReplicaUnderRecovery always
returns a newly instantiated object.
