> ServiceDiscoveryImpl.close() fails if the service was never started
> -------------------------------------------------------------------
>
> Key: CURATOR-101
> URL: https://issues.apache.org/jira/browse/CURATOR-101
> Project: Apache Curator
> Issue Type: Bug
> Affects Versions: 2.4.1
> Reporter: Steve Loughran
> Assignee: Jordan Zimmerman
> Priority: Minor
>
> the {{close()}} operator of ServiceDiscoveryImpl raises an
> {{IllegalStateException}} if you attempt to call it -this is a runtime
> exception and somewhat drastic on an operation that should be robust against
> odd states.
