Scott Harrington commented on LOG4J2-625:
-----------------------------------------
If it helps, I have compiled 1604433 and it works for me.
Previously as a workaround I had placed a Rewrite in front of the Socket
appender so that a new Log4jLogEvent would be created from each
RingBufferLogEvent.
I am now able to remove this workaround, and my "central" logging daemon is
still able to filter, layout, and append all deserialized LogEvents as expected.
Thank you all for your work toward RC2 (and before). Very impressive effort.
