This snippet works on MRI 1.9.3 - as per the examples in http://ruby-doc.org/core-1.9.3/Process.html#method-c-spawn

Process.spawn("ls nonexistent_dir", [:out, :err]=>["log", "w"])

Using jruby 1.7.9 (1.9.3p392) 2013-12-06 87b108a on Java HotSpot(TM) 64-Bit Server VM 1.7.0_45-b18 [darwin-x86_64]
it throws a TypeError

TypeError: wrong exec option: [:out, :err]
  _spawn_internal at org/jruby/RubyProcess.java:1067
            spawn at file:/Users/lorenzo/.rubies/jruby-1.7.9/lib/jruby.jar!/jruby/kernel19/process.rb:13

Process#spawn can accept arrays

This doesn't exactly fix the issue in #1651 but it at least allows it
to run now.

 => 3355
