open("|something", "w") does not open in write mode

Type: Bug
Status: Resolved
Priority: Major
Resolution: Fixed
Affects Version/s: None
Fix Version/s: JRuby 1.7.0.pre2
Component/s: None
Labels:
None
Environment:
jruby 1.7.0.preview1 (ruby-1.9.3-p203) (2012-05-17 c550df6) (Java HotSpot(TM) Client VM 1.6.0_26) [Windows 7-x86-java]

for instance this:

{{

{ a = "|ls.exe" b = open(a, 'w') sleep 3 b.write 'q' }

}}

'should' result in a closed pipe message, instead it results in

IOError: not opened for writing
write at org/jruby/RubyIO.java:1332
(root) at test.rb:4
