[jira] [Created] (ZOOKEEPER-1394) ClassNotFoundException on shutdown of client

ClassNotFoundException on shutdown of client
--------------------------------------------

                 Key: ZOOKEEPER-1394
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1394
             Project: ZooKeeper
          Issue Type: Bug
          Components: java client
    Affects Versions: 3.4.2
         Environment: OS X 10.7 java version "1.6.0_29"
            Reporter: Herman Meerlo
            Priority: Minor


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.
