No.  Unfortunately the jruby release is sort of a lie....  It doesn't
actually work on jruby.  I've been releasing a jruby version so that
webrat can use it's CSS to XPath conversion code, then fall back on
REXML.

We're working on a better jruby solution though.  We've got a branch
that uses FFI, and Charles Nutter has a branch with a Java
implementation.

I'm not sure what the status is on his branch.
