JRuby 1.7.11 not working in Windows 7 Enterprise version

[ambirag]

JRuby 1.7.11
Window 7 Enterprise
Service Pack 1
64 bit OS
When JRuby bin is set to the PATH and any command that starts with jruby -S fails with the error given below. This is severely blocking us from moving our cucumber/watir-webdriver automation to JRuby.
This is perfectly working fine on Mac, Win2k3, Win2k8.

D:\dev\trunk\ui\test\cucumber>jruby -S gem install bundler -f -v 1.3.5
NameError: undefined local variable or method `??' for main:Object

Can you test with a more recent JRuby version? We periodically verify JRuby on Windows and simple things like gem install should definitely be working.

I used all of 1.7.x on 64 bit win 7 for a majority of my testing. I am guessing this was an env issue of some kind. Since 1.7.x is EOL I am closing this.
