I get a pipe open null pointer exception after running

I downgraded Jruby 9.0.4.0 to jruby 1.7.23 and it works properly, but now I don't have the ruby 2.2 support that is in Jruby 9.x.x.x

Please try to add a testcase / make the tests run on jruby 9 ... I don't use it / don't know how to debug it, so any help would be awesome :)
