[jboss-jira] [JBoss JIRA] (JGRP-1888) FD_SOCK race condition during stop

[Ladislav Thon (JIRA)]

Ladislav Thon commented on JGRP-1888:
-------------------------------------

Just noting that the reproducer requires using Java 7, because it uses {{InetAddress.getLoopbackAddress()}}. Changing that to {{InetAddress.getLocalHost()}} seems to be fine (the test fails when unpatched and passes when patched).

> There is a race condition in FD_SOCK between stop() shutting down the pinger thread and the BroadcastTask.
> It first shuts down the broadcast task, and then the pinger thread.
> If the pinger thread generates a new suspected event in this interval, it re-starts the broadcast task, which creates a new thread suspecting that node repeatedly until the JVM exits.
