-------------------------------------------------------------------------------
Key: JRUBY-5422
URL: http://jira.codehaus.org/browse/JRUBY-5422
Project: JRuby
Issue Type: Bug
Components: win32ole, Windows
Environment: jruby 1.6.0.RC1 (ruby 1.8.7 patchlevel 330) (2011-01-24

Currently, if you start up a process, for example jruby.exe -e sleep in one
window
Then you run this in another window:
require 'rubygems'
require 'ruby-wmi'
piddy = WMI::Win32_Process.find(:first, :conditions => {'Name' =>
'jruby.exe'}) }
p piddy
700.times {sleep 1; piddy.SetPriority 64; print '.' }
(it starts) then kill the first process, jruby responds with:
# A fatal error has been detected by the Java Runtime Environment:
