logstash-core is included on the default installation of logstash. If you  
run bin/logstash-plugin list you will not see it. Buit if a newer version  
is a depedency for another plugin installation it pops up.

Logstash keeps a local directory storage for "gems" on  
logstash/vendor/bundle/jruby/1.9/gems and  
logstash/vendor/bundle/jruby/2.3/gems . On logstash6 there is only the 2.3  
directory as far as I have seen
