> Project: DistributedLog
> Issue Type: Bug
> Components: distributedlog-client
> Affects Versions: 0.4.0
> Reporter: Liang Xie
>
> Reading code, found there's a minor issue in DistributedLogMultiStreamWriter
> class. Currenty only flush()&write() have *synchronized*, but
> getLogRecordSetWriter miss the protection. so it would be possible get an
> obsolete writer just after flush() happened.
