JDK 8 will be EOL early next year (except for "premier support"). JDK 9, 10 and 11 all have issues for Solr and Lucene IIUC.
Also IIUC Oracle will start requiring commercial licenses for 11.
This Jira is to discuss what we want to do going forward. Among the topics:
- Skip straight to 11, skipping 9 and 10? If so how to resolve current issues?
- How much emphasis on OpenJDK .vs. Oracle's version
- What to do about dependencies that don't work (for whatever reason) with the version of Java we go with?
This may turn into an umbrella Jira with sub-tasks of course. Since JDK 11 has had a GA release, I'd also like to have a record of where the current issues are to refer people to.
