Hi Michael, Thank you for sharing. You are right about your approach to not customize the distribution.
Solr supports JDK8 and it latest versions (8.x) also JDK11. I would not recommend to use it with JDK9 or JDK10 as they are out of support in many Java distributions. It might be also that your database driver does not support JDK9 (check with Microsoft). I don’t see it that critical at the moment to have JDK8 on this production server, but since it is out of support you should look for alternatives. So if you are with Solr 8.x please go with JDK11 to have the latest fixes etc. Best regards > Am 09.09.2019 um 12:21 schrieb Friscia, Michael <michael.fris...@yale.edu>: > > I setup SOLR on Ubuntu 18.04 and installed Java from apt-get with default-jre > which installed version 11.
