MC-Log4J-Patcher

The goal of this project is to provide Minecraft players, and server owners, peace of mind in regards to the recently discovered Log4J exploit (CVE-2021-44228).
Currently this project looks for any Log4J format strings, not just jndi, and either replaces them or stops them from being logged entirely depending on your configuration.

See features, supported platforms, and more below.

I would much appreciate any help from others, whether it be by contributing or by suggesting features, platforms, etc. via an issue.
