Jenkins standing by to test this. If you aren't a maintainer, you can ignore this comment. Someone with commit access, please review this and clear it for Jenkins to run; then say 'jenkins, test it'.

not fully fixing the shutdown issue for me - still gets killed at least sometimes..
hangs in:
/vendor/bundle/jruby/1.9/gems/logstash-input-jmx-2.0.4/lib/logstash/inputs/jmx.rb:352:in `sleep'"

Any chance we get this PR merged? Fixes the issue for me (LS 5.0.0).
