ObserverTest.testObserver fails at particular point after several runs of ant junt.run -Dtestcase=ObserverTest
--------------------------------------------------------------------------------------------------------------

                 Key: ZOOKEEPER-1145
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1145
             Project: ZooKeeper
          Issue Type: Bug
    Affects Versions: 3.4.0
            Reporter: Eugene Koontz
            Priority: Blocker
             Fix For: 3.4.0
         Attachments: repeat.sh

Use the attached repeat.sh to run ObserverTest repeatedly by doing: 

src/repeat.sh ObserverTest

The test will will fail eventually after a few iterations; should be only a few minutes.

The line that fails in the test is: 

zk = new ZooKeeper("127.0.0.1:" + CLIENT_PORT_OBS,
                ClientBase.CONNECTION_TIMEOUT, this);

Attached as out.txt is the output showing a successful run, for comparison, followed by a
failed run.


Note that in the seconds before the test fails, in the following lines, that there is a 24
second gap in time (between 22:13:02 and 22:13:26):
