[jboss-jira] [JBoss JIRA] Closed: (JGRP-826) Unable to stop tomcat because of an IllegalStateException in jgroups threads

[Bela Ban (JIRA)]

     [ https://jira.jboss.org/jira/browse/JGRP-826?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban closed JGRP-826.
-------------------------

    Resolution: Rejected


This seems to be a log4j issue, which tries to create a LogEvent in the wrong classloader.
Probable solution: place the JGroups and log4j JARs into the ./lib dir
