Thanks @Randgalt, I figured that there was a good place to put this, but
couldn't remember where it should be. @njhill can you refactor the sequential
number extraction into org.apache.curator.utils.ZKPaths class? Or, if you don't
have time, let me know and I'll get it done.
> Sequential PersistentNodes with protection don't resync after reconnection

> Key: CURATOR-483
> URL: https://issues.apache.org/jira/browse/CURATOR-483
> Project: Apache Curator
> Issue Type: Bug
> Components: Recipes
> Affects Versions: 4.0.1
> Reporter: Nick Hill
> Priority: Major
>
> When using a {{PersistentNode}} with a sequential creation mode (in my case
> ephemeral but I think persistent would be the same) and "protection" turned
> on, unexpected duplicate znodes get created upon reconnection after a
> disconnect (without the sequence suffix), rather than it just taking
> ownership of the previously created znode.
> I tracked down the cause of this and have made a simple fix.
