Redirecting stderr to stdout in spawn gives an exception.

$ jirb
irb(main):001:0> Process.spawn('ls -al',:err => :out)
Java::JavaLang::ArrayIndexOutOfBoundsException: -2
from org.jruby.util.io.PopenExecutor.run_exec_dup2(PopenExecutor.java:789)
from org.jruby.util.io.PopenExecutor.execargRunOptions(PopenExecutor.java:986)
from org.jruby.util.io.PopenExecutor.spawnProcess(PopenExecutor.java:113)

Same thing happens if you use STDERR => STDOUT or 2 => 1 (instead of :err => :out) as shown in http://ruby-doc.org/core-2.2.2/Process.html#method-c-spawn

This was run on:
$ jruby -v
jruby 9.0.4.0 (2.2.2) 2015-11-12 b9fb7aa OpenJDK 64-Bit Server VM 24.91-b01 on 1.7.0_91-b02 +jit [linux-amd64]

It appeared to work ok for me on 9.1:

$ jruby -e "Process.spawn('ls -al',:err => :out)"
total 490264

drwxr-xr-x   18 headius  staff        612 Mar  4 12:06 .git

If it's still broken for you with a 9.1 snapshot from http://ci.jruby.org, reopen this issue.
