Would it be possible to test `public Request checkUpgradeSession(Request
request)` directly in addition to this integration style test?
> Upgrading to a global session fails with a multiop
> --------------------------------------------------
>
> Key: ZOOKEEPER-2725
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2725
> Project: ZooKeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.5.2
> Reporter: Brian Nixon
>
> On an ensemble with local sessions enabled, when a client with a local
> session requests the creation of an ephemeral node within a multi-op, the
> client gets a session expired message. The same multi-op works if the
> session is already global. This breaks the client's expectation of seamless
> promotion from local session to global session server-side.
