Nashorn's bug with using `with` statement

sample.js

function Foo() {
  this.bar = "bar";
  this.baz = "baz";
}

Foo.prototype._h = function(str) {
  print("expect `bar`: " + this.bar);
}

Foo.prototype._e = function() {
  print("expect `baz`: " + this.baz);
}

function makeFunction() {
  return new Function("with(this) { return _h(_e()); }");
}

var fn = makeFunction();
var foo = null;
for (var i=0; i < 20; i++) {
  foo = new Foo();
  fn.call(foo);
}
