Google is working on J2Cl (as mentioned already by Emilio), which is (will 
be) a transpiler from Java to ES6 (as understood by the Closure Compiler, 
hence "Cl" in the name; the Closure Compiler –or Babel or whatever– then 
being possibly used to transpile ES6 to ES5 or ES3, and possibly bundle and 
optimize all the code).
J2Cl is expected to be the new compiler in GWT 3.0.

Any ES3 or ES5 script is a valid ES6 script; all JS engines supporting ES6 
do "only" support ES6, there are no "modes" to be triggered by some 
configuration or what not (contrary to the old E4X for instance).
