relative_path_from returns errors for "C:/" and "C:\\"
------------------------------------------------------
Key: JRUBY-3621
URL: http://jira.codehaus.org/browse/JRUBY-3621
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.2, JRuby 1.3RC1
Environment: Windows XP, Java JRE6
Reporter: Mark Donnelly
This fails on Windows:
Pathname.new('C:/').relative_path_from(Pathname.new("C:\\test"))
This came from my attempt to run script/generate during the RailsConf tutorial.
Here's the full stack trace:
