Steffen Offermann commented on LOG4J2-961:
------------------------------------------
[~rpopma]:
I'm afraid this IS a very serious show stopper for us, as the WebSphere
installation our application runs on is not ours but managed by our customers.
:(
Any new information on how to solve the issue? The latest Log4j version
(2.11.2) still doesn't work.
