[jboss-jira] [JBoss JIRA] Commented: (JGRP-1205) Retransmitter reset does not prevent new task addition after chanel close

Bela Ban commented on JGRP-1205:
--------------------------------
OK, I changed NakReceiverWindow.destroy() [renamed from reset()] to set 'running'
to false. When !running, add() will not add a message, therefore the Retransmitter
won't add it, either. Messages can still be removed though

Key: JGRP-1205
URL: https://jira.jboss.org/browse/JGRP-1205
Project: JGroups
Issue Type: Bug
Affects Versions: 2.6.15, 2.7, 2.8, 2.9
Reporter: Vladimir Blagojevic
Assignee: Bela Ban
Fix For: 2.10
Sometimes, messages are being added to the Retransmitter *after* a channel has been
closed. This can happen if OOB messages are being passed around at the time a channel is
leaving a group. The problem occurs in that messages are added after
Retransmitter.reset(). Normally, the timer is also stopped when the channel is
disconnected, but since the Timer is shared amongst all channels, any messages added to
Retransmitter after reset() just continue to be requested because the timer that those
tasks were scheduled on did not die.
This can be solved by either specifically stopping the Retransmitter or giving each
ProtocolAdapter their own Timer which is then shutdown on channel disconnect.
