Logstash engineer here and owner of the jdbc* plugins. We have had some problems with loading drivers recently (fixed now but not released).

Please confirm that the info on the FAQ wiki page is correct with respect to versions and JDK 9,10,11.

I'm especially interested in the sections "How can I load a ResourceBundle from the Rails config directory ?" and "Why do I get ClassNotFoundException when I call java.lang.Class.forName from Ruby?"

Not the Rails bit obviously, but the appending to the $CLASSPATH - does JRuby have a utility to prefix the file or folder correctly and check that it exists?

@guyboertje Perhaps your issues would be helped by a change to the launch script we made in 20e4278? We were mistakenly putting everything in $CLASSPATH into the module path which appears to have some odd impacts on loading.

@headius headius added this to the JRuby milestone May 28, 2019
