"ConnectionLoss for /dog"

Zookeeper v3.5.0-alpha experiences an error when trying to create a simple data node.

Versions before and after 3.5.0-alpha work just fine, but this specific version oddly fails to create data nodes.

https://github.com/mcandre/docker-zookeeper/tree/3.5.0-alpha

Trace:

```
