Readd in jline support for jruby on on windows. It will attempt to use the jline associated with the the jruby 1.7.* code path, and then the jruby 1.6.* code path. However this may still cause issues when other libraries have also loaded jline (i.e. Scala) in which case the code will revert to using a black and white console
