jruby error on init; error on IO.popen(); fails when cmd is string, works when cmd is array

[bwalsh]

note brackets around cmd [] cmd is a string or an array as follows.

      @engine = IO.popen([cmd],"w+")

environment

java -version java version "1.7.0_09" Java(TM) SE Runtime Environment (build 1.7.0_09-b05) Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)

jruby -v jruby 1.7.2 (1.9.3p327) 2013-01-04 302c706 on Java HotSpot(TM) 64-Bit Server VM 1.7.0_09-b05 [Windows 7-amd64]

trace

I've added a few puts() statements to trace ...

  puts "R cmd #{cmd}"
     begin
       @engine = IO.popen(cmd,"w+")
     rescue Exception => e  
        puts "e.message=#{e.message}"
        puts e.backtrace
        puts e.inspect  
        raise e.message
     end  
  puts "R @engine #{@engine}"

with the brackets ...

jruby -S irb irb(main):001:0> require "rinruby" R start R require java R platform windows-java R executable "C:/Program Files/R/R-2.15.2/bin/i386/Rterm.exe" R loaded readline R cmd "C:/Program Files/R/R-2.15.2/bin/i386/Rterm.exe" --ess --slave R @engine #IO:0x51a4f310

without the brackets ...
