Hallo, as with OSGI, there is currently no support for running Lucene in Java 9. This requires a complete restructure of the Lucene/Solr package structure and that's not going to happen in the next release. You should compile and run Lucene with the standard classpath where it works without any problems! Don't put the JAR files as auto-modules on the module-path (neither at runtime nor at compile time). So stay with classpath and all should be fine.
FYI, when placed on classpath, Apache Lucene and Solr (latest 6.x) versions are compatible with the module system and its restrictions (it works with illegal-access=deny and we run our tests with it), but you cannot make modules out of the JARs. One solutions is possible: Combine all Lucene JARs to one Uber JAR file using Maven Shade plugin and use that as a "single huge module".
