Affects Versions: JRuby 1.6RC2

now, where it worked using JRuby 1.5.6.

[INFO] ----------------------------------------------
{noformat}
If the same script is executed outside of the context of maven, this error is
avoided.
The maven process does not fork the jruby that is running
rspec+capybara+ffi+nokogiri, but runs it in-process.
Having maven run the ruby with fork=true does not improve the situation, oddly.
I will attempt to work up a small test project for your experimentation.
