      Description

      underscore_linker.js sample in $jdk9/nashorn/samples/dynalink/ directory fails after recent dynalink changes for JDK-8168005

      This sample didn't output anything after dynalink changes. After instrumenting underscore_linker.js to print $ERR, I got the following stack trace:

       jjs underscore_linker.js
