    Description

      Starting with Lucene 9.1.0, Lucene now logs certain warnings and errors using Java Util Logging (JUL). Upgrade notes: https://lucene.apache.org/core/9_1_0/MIGRATE.html

      For Solr's Log4J setup to include these logs, we must follow Log4J's JUL instructions and set -Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager when starting Solr. We will also need to include the log4j-jul jar in lib-ext with the other logging jars.
