Ralph Goers commented on LOG4J2-2241:
-------------------------------------
I tried building the example but it failed with the errors below. However, I
have a couple of observations:
1. The errors you show have nothing to do with SLF4J. The failure happens
trying to create LogManager.
2. The error is trying in your example looks like a duplicate of LOG4J2-2129,
which is fixed in both release-2.x and master. Please try one of those and see
if the error still occurs.
