> Project: ZooKeeper
> Issue Type: Bug
> Components: java client
> Affects Versions: 3.4.2

> When close() is called on the ZooKeeper instance from a ContextListener
> (contextDestroyed) there is no way to synchronize with the fact that the
> EventThread and SendThread have actually finished their work. The problem
> lies in the SendThread which makes a call to ZooTrace when it exits, but that
> class has not been loaded yet. Because the ContextListener could not
> synchronize with the death of the threads the classloader has already
> disappeared, resulting in a ClassNotFoundException.
> My personal opinion is that the close() method should probably wait until the
> event and send thread have actually died.
