Regexp caches don't invalidate if $KCODE changes
------------------------------------------------

                 Key: JRUBY-4889
                 URL: http://jira.codehaus.org/browse/JRUBY-4889
             Project: JRuby
          Issue Type: Bug
          Components: Core Classes/Modules
    Affects Versions: JRuby 1.5.1
            Reporter: Nick Sieger
            Assignee: Nick Sieger
             Fix For: JRuby 1.6


$KCODE doesn't change often, but ActiveSupport::Multibyte tests change it 
frequently. This causes issues with literal caching that doesn't take $KCODE 
changes into account. Example failure:
