My best guess at this point without more details is that you’ve hit on
either some Rails compatibility bug, or JRuby compatibility bug, or a
combination. A new JRuby-Rack release is needed soon, I’ll try to get
to it in the next week or so. Until then, if you could file a bug at
http://kenai.com/jira/browse/JRUBY_RACK with some more details, I’d
appreciate it!

Thanks Nick. Unfortunately i dont have a lot of other details, except
the environment, but will file a more generic bug.
