                 URL: http://jira.codehaus.org/browse/JRUBY-5685

          Issue Type: Bug
            Reporter: Aman Gupta
            Assignee: Thomas E Enebo


Instead of passing through the string '*' to the process, no arguments are sent.

{noformat}
jruby-1.6.0 :015 > IO.popen4("echo", "123"){|pid,i,o,e| o.read }     
 => "123\n" 
jruby-1.6.0 :016 > IO.popen4("echo", "123", "*"){|pid,i,o,e| o.read }
 => "\n" 
{noformat}
