Q:

JRuby 1.5.5 keeps throwing jruby: unknown option --disable-gems

After a clean install of jRuby 1.5.5, I cannot run jruby -v from the command line without getting the following error:
jruby: unknown option --disable-gems
I didn't specify that option so I don't know where it's coming from. 
This also precludes me from using jruby in Netbeans. 
Any ideas?

A:

It was completely my oversight.  I had added the --disable-gems as an environment variable in an attempt to speed up rails on a windows machine.  I completely forgot.
