Update[Sep 13, 2022]: Log4j is no longer used in the IntelliJ platform. For a drop-in replacement, please look at reload4j.
The repository contains a fork of Apache Log4j 1.2 library
with just a single change on top: removal of potentially problematic org.apache.log4j.net package.
Artifacts are published to the IntelliJ dependencies
repository with coordinates org.jetbrains.intellij.deps:log4j. The first build from this repository has the version
1.2.17.3; earlier versions are manual patches of the stock .jar.
