> Project: Solr
> Issue Type: Bug

> For many project use the log4j, actually solr use slf logger framework, slf
> can easy to integrate with log4j by design.
> Solr use log4j-over-slf.jar to handle log4j case.
> This jar has some issues.
> a. Actually last invoke slf to print the logger (For solr it is
> JDK14.logging).
> b. Not implement all log4j function. ex. Logger.setLevel()
> c. JDK14 log miss some function, ex. thread.info, day rolling
> Some dependence project had been used log4j that the customer still want to
> use it. JDK14 log has many different with Log4j, at least configuration file
> can't reuse.
> The bad thing is log4j-over-slf.jar conflict with log4j. If use solr, the
> other project have to remove log4j.
> I think it shouldn't use log4j-over-slf.jar, still reuse log4j if customer
> want to use it.
