Ranjit Dsouza commented on LOG4J2-2316:
---------------------------------------
Yes, let's take this forward
I will use version 2.11.0 and see if there is an improvement. I will get back
in case I see the issue recur again.
Can you guide me on version 2.11?
should we wait for the next upcoming stable version after 2.11, or is the
current version 2.11 good enough?
Thanks
