Cannot move a Tempfile after creation
-------------------------------------
Key: JRUBY-3843
URL: http://jira.codehaus.org/browse/JRUBY-3843
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.3.1
Environment: becherovka:~% uname -a
Darwin becherovka.local 9.7.0 Darwin Kernel Version 9.7.0: Tue Mar 31 22:52:17

jruby 1.3.1 (ruby 1.8.6p287) (2009-07-28 6586) (Java HotSpot(TM) 64-Bit Server
VM 1.6.0_13) [x86_64-java]
Reporter: Otto Hilska
Given the following test code:
require 'fileutils'
require 'tempfile'
# Creating a normal file and then moving it to a new path.
normal = File.new("testing-normal-file", "w")
normal.write "Hello world"
normal.close
FileUtils.mv(normal.path, "final-destination-for-normal")
FileUtils.rm("final-destination-for-normal")
# Creating a temp file and then moving it to a new path (FAILS).
temp = Tempfile.new("testing-temp-file")
temp.write "Hello world"
temp.close
FileUtils.mv(temp.path, "final-destination-for-temp")
FileUtils.rm("final-destination-for-temp")
Ruby 1.8.6 vs. JRuby 1.3.1 I get the following error:

I think this is quite major, because I can't use buildr because of this problem.
There's something funny about the reproducibility of this problem. I don't know
if it's about the OS X version or what, but I can't reproduce the problem with
our iMacs and older MacBook Pros, but it is broken with unibody MacBook Pros
and Mac Minis. :)
It's not about file permissions either. I can give an additional parameter to
Tempfile creation to change the tempdir, but the problem stays:
