Jeremy Landis commented on SLF4J-373:
-------------------------------------

I would close this too.  It's not a bug.  Do you want to log to log4j 1.2 or jdk 1.4?  You have to pick one and the link tells you why.  So in your case, exclude one of them.  If this is due to some classloading issue in EAR where those are in different WARs, while I cannot help much I would ask why are you still using EARs to start with?  Almost every EAR I've ran into in my development career has been incorrectly used and completely unnecessary and with microservices all the rage, there is really no compelling reason to use them.  But if you must, there are ways to fix the issue you see without having a fix to this library.
