Healers Log4J Proxy is conflicting with Forge Essentials LoggingHandler.

https://github.com/ForgeEssentials/ForgeEssentials/blob/1.12.2/develop/src/main/java/com/forgeessentials/util/output/LoggingHandler.java

This causes a class not found exception cause Forge Essentials uses the same codepath (https://github.com/Glease/Healer/blob/master/src/main/java/net/glease/healer/Healer.java#L99) to inject it's own appenders into the log4j config.

Attached is the crash report in question https://pastebin.com/ZyzjbYck
Removing the mod allows the server to start up however, it would be ideal for the mod to be compatible due to the criticality of the log4j issues!

forge 14.23.5.2859 1.12.2 Windows 10

Not sure if I'm using this wrong or not, but I've downloaded Healer-1.1.0.jar from Releases and tried to put it in mods or in mods\1.7.10.
In both cases, running ${date:YYYY} on singleplayer prints 2021 onto the game log which is not supposed to happen.
Any idea what's going wrong?
Thanks!
