Log4j 1 reached End-Of-Life on August 2015. The reload4j project provides a drop-in replacement for Log4j 1.x with maintenance and security fixes.

Java Support

The only supported Java version is Java 8 and above.

  • Log4j 2.13.0 and greater require Java 8 or above.
  • Log4j (2.4 - 2.12.2) require Java 7 or above.
  • Log4j 2.12.2 was released as an emergency release (to fix CVE-2021-45046 and CVE-2021-44228) and is the last 2.x release to support Java 7. The Log4j team no longer supports Java 7, so this release (while fixing the vulnerability) is no longer supported.
  • Log4j 2.3 was the last 2.x release to support Java 6.
