Does a handlebars.js implementation in java exist? [closed]

Question

Currently I'm using Mustache templates ( http://mustache.github.com/ ) both on the client and server-side, using javascript and java implementation respectively.

However, there are some limitations in Mustache which the relatively new Handlebars.js ( http://www.handlebarsjs.com/ ) tries to overcome.

However as far as I see it handlebars only has a javascript implementation as of yet. Anyone knows of an (experimental) java-implementation of Handlebars?
