      Converting the "monster" string located in http://amos.fr.oracle.com/jmgt/tmp/jfdenise/cache.json into JS Object takes up to 1.5 minutes.
      The tescase (that requires nodejar to load the JSON file) is attached.

      CPU time is spent in getting PropertyMap properties (17% of time), computing PropertyMap hashcode (50% of time) and Property hashcode (20%)
