>          Issue Type: Bug
>          Components: Framework
>            Reporter: Nikita Ryanov

> According to java doc framework should return empty string if namespace is empty instead of null:
>  
> {code:java}
> /**
>  * Return the current namespace or "" if none
>  *
>  * @return namespace
>  */
> public String getNamespace();
> {code}
>  
> If namespace is claimed from CuratorFramework client directly all is ok, but if NamespaceFacade is used then null is returned. 
> How to reproduce:
> {code:java}
> RetryPolicy policy = ...;
> CuratorFramework client = CuratorFrameworkFactory.newClient("connectionString", policy);
> CuratorFramework clientWithNamespaceFacade = client.usingNamespace(null);
> clientWithNamespaceFacade.getNamespace(); // <- expected "", but got null
> {code}
>
