Hi,

The problem was two-fold.

1. Minor JRuby incompatibility. 'sane' gem is doing pretty low-level
tricks with core classes. While investigating this a nice way to
speed-up some very common Array operations has been discovered (from
25% to 200%!), which is all good. :)

2. whichr doesn't detect the Windows pratform properly on JRuby. I
keep seeing this over and over again, so I even wrote a blog entry to
bring attention to this problem:

http://blog.emptyway.com/2009/11/03/proper-way-to-detect-windows-platform-in-ruby/

'whichr' gem needs to be corrected.

Thanks,
--Vladimir

P.S. Thanks for filing the bug in our JIRA:
http://jira.codehaus.org/browse/JRUBY-4205
