Different behaviour for $" between JRuby and MRI
------------------------------------------------
Key: JRUBY-5186
URL: http://jira.codehaus.org/browse/JRUBY-5186
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.5.3
Reporter: bob mcwhirter
Assignee: Thomas E Enebo
With MRI, adding a string to $" will allow a requirement of that path to
succeed as a no-op. Under JRuby, seems to not be the case.
