# This patch fixes a problem that exists in JRuby prior to 1.7.11 where the
# ruby binary path used by rubygems is malformed on Windows, causing
# dependencies to not install cleanly when using `.\bin\logstash.bat deps`.
# This monkeypatch can probably be removed once it's unlikely that people
# are still using JRuby older than 1.7.11.
