upstream "sinatra" package incompatibility: An unexpected error occurred! {:error=>#<ArgumentError: wrong number of arguments (given 3, expected 1..2)>

[mmguero]

Logstash no longer starts as one of the plugins we're installing pulls an updated version 2.2.0 of the sinatra package causes the error message on startup:

See elastic/logstash#13777 and jruby/jruby#7102

In the meantime we need to edit Logstash's Gemfile.lock to use the unaffected previous 2.1.0 version.
