[jboss-jira] [JBoss JIRA] (JGRP-1585) Add support for log4j2

Add support for log4j2 ---------------------- Key: JGRP-1585 URL: https://issues.jboss.org/browse/JGRP-1585 Project: JGroups Issue Type: Task Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.3 log4j has some heavy synchronization, which can sometimes lead to code blocking up to 30 seconds (see [1]). Investigate whether we should switch to log42 [2]. Perhaps we can simply program against the API (30K) and not even ship the implementation ?
