Dir[] results in NPE depending on permissions
---------------------------------------------
Key: JRUBY-2997
URL: http://jira.codehaus.org/browse/JRUBY-2997
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1.4
Environment: Solaris 10, JRuby 1.1.4
Reporter: Daniel Berger
This simple script on Solaris 10 demonstrates the problem:
{noformat}
Dir["/proc/0/path/*"] # jtest.rb
{noformat}
The /proc/0 directory, and all files in it, are owned by root. If I try to read
that file as a non-root user I get this:
{noformat}
>jruby jtest.rb
