Matt Sicker commented on LOG4J2-1902:
-------------------------------------
You can use log4j-1.2-api for compatibility with libraries that log directly to
the log4j 1.x classes, though it doesn't cover the internals of log4j 1.x if
there's any programmatic configuration going on. Either way, that won't affect
the shutdown hook bit you mentioned.

> I want to disable the shutdown hook, as I'm having trouble in tomcat 7,
> websphere 8, as app logs nothing to the file. The way I'm making it work is
> restarting the application container, which is causing downtime to other
> services running on the same container.
> The doc https://logging.apache.org/log4j/2.x/manual/webapp.html says
> log4j2-web jar is what disables the shutdown hook but not working for me.
