   Hi @joshelser , yes I did test shell on my local machine, but just for a sanity check, I tested again.
   - Built master with this commit on top (mvn clean install -DskipTests assembly:single)
   - start-hbase.sh / hbase shell and issue comands create/list/put/scan
   
   I restarted the pre-commit job because it was flaky at the time, and I saw timeouts in the logs, and/or some dockr problems. No test failures or other errors though. Still, I couldn't get a clean build.
   
   As for JRuby docs, this is what I written together, please let me know what is missing/should be changed. (We could list all the bugfixes, but it's more than a 1.000, and the below link has it all). Thanks!
   
   For changelog please check https://www.jruby.org/news
   
   Main points:
   JRuby 9.2.0 minor release:
   
   Ruby 2.5 language and stdlib support
   225 issues fixed for 9.2.0.0
   JRuby versions up to 9.2.13.0 had various bugfixes, seucirty fixes, performance improvements (memory reduction, runtime generations), IO improvements, basic support for java11,
   
   Main gems changes:
