Title: Fix for NullPointerException in JRuby when running in 1.9 mode

In the latest version of JRuby running in 1.9 mode, you'll get a NullPointerException when requiring newrelic_rpm due to NewRelic::LanguageSupport::Control forcing YAML::ENGINE.yamler to 'syck' when parsing the new_relic.yml config file.

syck support in JRuby is poor/non-existent when running in 1.9 mode (see https://github.com/padrino/padrino-framework/issues/649#issuecomment-2083545).
