We are aware of the end of life status, but it's not a trivial exercise to upgrade. Multiple issues have been filed to upgrade log4j in Solr, this is the one that's left after resolving duplicates: https://issues.apache.org/jira/browse/SOLR-7887 Presumably we're going to need a new LogWatcher implementation for log4j2 before we can complete the log4j upgrade. I know almost nothing about that code. SOLR-7887 has a work in progress patch that might implement that watcher, which I have not looked at in depth yet.
