Top 10 Java Log4j Projects

  • Apache Log4j 2

    Apache Log4j 2 is a versatile, feature-rich, efficient logging API and backend for Java.

    Project mention: Hackers exploited Windows 0-day for 6 months after Microsoft knew of it | news.ycombinator.com | 2024-03-05

    I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

    Project mention: slf4j or System.Logger? | /r/java | 2023-07-06

    I had the same challenge deciding what option would be the beste and attempted to solve it with an mini library which just attempts slf4j, log4j2 and fallbacks to java itil logging. It was useful for this kind of situation, not quite sure whether it is useful for others though... see here for more https://github.com/Hakky54/yaslf4j
