are both vendor/jruby and logstash-core/lib/jars/jruby-complete-9.1.13.0.jar required?

[colinsurprenant]

We actually use two JRuby distributions in logstash:

• the binary distribution installed in vendor/jruby
• the complete JRuby jar in logstash-core/lib/jars/jruby-complete-9.1.13.0.jar

Are both strictly required? couldn't we get rid of vendor/jruby and only rely on logstash-core/lib/jars/jruby-complete-9.1.13.0.jar ?

@colinsurprenant yea theoretically we could get rid of vendor/jruby. We actually did get rid of it in a number of places lately (integration tests, x-pack specs, x-pack integration tests).
Unfortunately there's still spots left that will require a Java wrapper to get rid of the scripting vendor/jruby provides. At this point it's at least (and I'm probably missing some) the plugin manager (this one is the only one that's gonna be a little more work to wrap though), the acceptance tests and the license checks.
