> See ZOOKEEPER-1449 for background on this issue. The main problem is that 
> during server recovery 
> org.apache.zookeeper.server.persistence.FileTxnLog.FileTxnIterator.next() 
> does not indicate if the available logs are valid or not. In some cases (say 
> a truncated record and a single txnlog in the datadir) we will not detect 
> that the file is corrupt, vs reaching the end of the file.
