[jira] [Assigned] (CASSANDRA-5689) NPE shutting down Cassandra
trunk (cassandra-1.2.5-989-g70dfb70)
[ https://issues.apache.org/jira/browse/CASSANDRA-5689?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Ellis reassigned CASSANDRA-5689:
-----------------------------------------
Assignee: Ryan McGuire
I don't see how this can happen since stop should only call close once:
{code}
public void stop()
{
if (isRunning.compareAndSet(true, false))
close();
}
{code}
Ryan, can one of your team reproduce?
