leader election recipe sample code - dispatchEvent invocations can get out of
order
-----------------------------------------------------------------------------------
Key: ZOOKEEPER-1405
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1405
Project: ZooKeeper
Issue Type: Bug
Components: recipes
Affects Versions: 3.4.3
Reporter: Robert Varga
Since the process method is not synchronized in
org.apache.zookeeper.recipes.election.LeaderElectionSupport, therefore there is
a race condition where events coming in from the watch may overtake the events
dispatched during the start method.
A solution to ensure that events dispatched during the start method are handled
before any watch-based events is to make the process method synchronized.
