Hi, Apache Lucene/Solr uses Java 9 to have some pre-release checks that everything works at least with Java 8 and 9 (our nightly smoke testing jobs). Apache Lucene and Solr are supported from Java 8 on and it contains some "hacks" to support the module system and changed internal APIS starting with Java 9 (forceful unmapping).
