Hi Rory, Apache Lucene/Solr 7.0 will be the first version that "offcially" supports Java 9. It will come out the next weeks. I fixed the startup scripts of Apache Solr and we also tested GC logging successfully:
https://issues.apache.org/jira/browse/SOLR-8689 https://issues.apache.org/jira/browse/SOLR-10184 https://issues.apache.org/jira/browse/SOLR-8689 We finally fixed the issues with Apache Hadoop integration, as upstream updated their library to not fail on the plain "9" as version number with StringIndexOutOfBoundsException. Apache Lucene and Solr 6.6.1 will also be released soon, but it is not yet decided if we backport everything (the Hadoop upgrade was committed already, the shell scripts of windows not yet).
