You may be hitting the issue mentioned in the blog at:
http://blog.arungupta.me/2009/07/totd-87-how-to-fix-the-error-undefined-method-new-for-racklockstring-caused-by-warblerjruby-rack/
As suggested, upgrading to the latest Rack version might solve your
problem as jruby-rack bundles an older version of Rack.
Thanks,
