             Summary: Upgrade log4j
                 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 ?
