[jboss-jira] [JBoss JIRA] (JGRP-1871) NPEs due to non-volatile Protocol variables

NPEs due to non-volatile Protocol variables ------------------------------------------- Key: JGRP-1871 URL: https://issues.jboss.org/browse/JGRP-1871 Project: JGroups Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.4.5, 3.5 Reporter: Paul Ferraro Assignee: Paul Ferraro In WildFly a given channel is created in one thread, but is potentially started in a different thread. Unfortunately, many of the protocol variables that are set during Protocol.init() are non-volatile. This can cause unexpected behavior as seen in WFLY-3727. To ensure clean initialization for multi-threaded environments like WF, all non-final variables within every JGroups' Protocol should be volatile.
