According the issues linked the issue was resolved and the latest versions of the logmanager and log4j-jboss-logmanager should be in the current release.
Changing to WONTFIX because this is not actually in EAP 6. Honestly I probably shouldn't have opened this BZ to begin with because it should be an internal PRODMGT Jira until it's been approved for implementation by PM. If it does get worked on in the future, we can open a new BZ at that time (I guess).
