Issue Type: Bug Bug
Affects Versions: JRuby 1.7.4
Assignee: Unassigned
Components: Core Classes/Modules

Description:

Ran into another bug while trying to get rails testsuite running on JRuby. Like, previous one this too is caused by non-english chars.

Problem

when StaticTests#test_served_static_file_with_non_english_filename is run, it raises the following Exception

IllegalArgumentException

I looked into this further and managed to isolate the issue to this line of Rack::File



last_modified = F.mtime(@path).httpdate



With this new information, I was able to reproduce this behaviour directly from command-line



$ jruby -e'puts File.mtime "/home/gaurish/code/repo/rails/actionpack/test/fixtures/public/foo/こんにちは.html"'



For the intended/expected behaviour it should return DateTime Object as seen below on MRI



$ ruby -e'puts File.mtime "/home/gaurish/code/repo/rails/actionpack/test/fixtures/public/foo/こんにちは.html"'
