Tell me please. How on JS do this:
 new TypeToken <Map <String, Object >> () {}. getType ()

First you have to make Nashorn load the jar containing the class, but then I think you say

var myTypeToken = new com.google.gson.reflect.TypeToken() {};

myTypeToken.getType()

The first line isn't valid javascript, but Nashorn has a syntax extension to let you create anonymous classes.  See the fourth entry here:
