      Description

        Reported by Walter Higgins on nashorn-dev:

        http://mail.openjdk.java.net/pipermail/nashorn-dev/2014-February/002745.html

        The problem is that the global variable is configurable but callsites using it will not be properly guarded.

        Script to reproduce:

        global = this;

        function test() {
          global.self = 123;
          try {
            print(self);
          } finally {
            delete global.self;
          }
        }

        test();
        test();
        test();
