[GitHub] [zookeeper] kezhuw opened a new pull request, #1896: ZOOKEEPER-3996: Fix flaky ReadOnlyModeTest.testConnectionEvents

kezhuw opened a new pull request, #1896:
URL: https://github.com/apache/zookeeper/pull/1896

   The same watcher was resued across different clients. It is hard to
   know which event will last during verification, disconnected from old
   client or connected from new client.
   
   A brand new watcher solves this.

   The old test could not last 10 runs after adding `Thread.sleep(700)` before `watcher.waitForReadOnlyConnected(5000)`. The assertion message proves that "disconnected from old client" comes after "connected from new client".
   
   After patch with `watcher = new CountdownWatcher()`, the test last 100 runs with no failure.
