Dir.new does not work for directories inside jar file
-----------------------------------------------------
Key: JRUBY-3478
URL: http://jira.codehaus.org/browse/JRUBY-3478
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.6, JRuby 1.2
Environment: JRuby 1.1.6 and JRuby 1.2.0RC2, Java 1.6.0_11, Linux
2.6.27-13-generic #1 SMP x86_64 GNU/Linux
Reporter: Manfred Usselmann
Dir.new fails with 'Errno::ENOENT - No such file or directory - 'path' is not a
directory' if path denotes a directory inside a jar file.
Example:
dir = File.expand_path(File.dirname(__FILE__)) + '/database/migrations/'
puts "#{Dir.new(dir).inspect}"
==>
Error in application
Errno::ENOENT - No such file or directory -
file:/home/manfred/projects/my_app/package/jar/my_app.jar!/database/migrations/
is not a directory
This also happens if I remove 'file:':
puts "#{Dir.new(dir.gsub('file:', '')).inspect}"
==>
Error in application
Errno::ENOENT - No such file or directory -
/home/manfred/projects/my_app/package/jar/my_app.jar!/database/migrations/ is
not a directory

I noticed that problem while using Sequel migrations:
When I run my app via the jar file sequel migrations fail while
searching for migration classes inside the given directory:

"File.directory? returns false for directories inside a jar"
dir = File.expand_path(File.dirname(__FILE__)) + '/database/migrations/'
puts "dir: #{dir} directory? #{File.directory? dir}"
==> "dir:
file:/home/manfred/projects/my_app/package/jar/my_app.jar!/database/migrations/
directory? false"
puts "dir: #{dir.gsub('file:', '')} directory? #{File.directory?
dir.gsub('file:', '')}"
==> "dir:

directory? false"
