[jboss-jira] [JBoss JIRA] Resolved: (JGRP-300) NAKACK.send() doesn't need to be synchronized

NAKACK.send() doesn't need to be synchronized --------------------------------------------- Key: JGRP-300 URL: http://jira.jboss.com/jira/browse/JGRP-300 Project: JGroups Issue Type: Task Affects Versions: 2.3 SP1 Reporter: Bela Ban Assigned To: Bela Ban Priority: Minor Fix For: 2.4 NAKACK.send() currently calls passDown(evt) in a synchronized(sent_msgs) statement. However, this is not necessary (contrary to handleMessage() which needs to pass messages up in the order of sequence numbers) because messages can be sent un-ordered. The receivers will order the messages anyway, so if we sent 1,3,2,4 due to thread premption, the receivers will order them and deliver them as 1,2,3,4. BENEFIT: the less synchronization, the less probability of deadlocks
