Stefaan Dutry commented on WW-4851: ----------------------------------- [~lukaszlenart] {quote} It's just a WARN but still users will complain {quote} true, i've searched for half a day on the problem already when updating struts2-bootstrap. I didn't find a solution for it then. If you do find a solution, can you post the fix (or a link to it) in a comment on this issue? That way i can apply it elsewhere too. I'll try looking for a solution again later this week. I'll keep you posted if i find anything. > Upgrade to Log4j2 2.9.0 > ----------------------- > > Key: WW-4851 > URL: https://issues.apache.org/jira/browse/WW-4851 > Project: Struts 2 > Issue Type: Dependency > Reporter: Stefaan Dutry > Priority: Trivial > Fix For: 2.5.14 > > > version {{2.9.0}} was released on {{2017-08-26}} > [changelog|https://logging.apache.org/log4j/2.0/changes-report.html#a2.9.0] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
