> We have an integration test suite that starts up an embedded version of
> zookeeper as part of a suite of services.
> However because it doesn't register a shutdown handler, we get lots of
> warnings that look like this
> 17-05-30 15:04:56 achambers.local ERROR
> [org.apache.zookeeper.server.ZooKeeperServer:472] - ZKShutdownHandler is not
> registered, so ZooKeeper server won't take any action on ERROR or SHUTDOWN
> server state changes
> My java is a bit rusty but I think I can't create one of these shutdown
> handlers from outside the "org.apache.zookeeper.server" package because the
> constructor has not been marked "public". Would it be possible to do so?
