Loop over java Map with scalate's mustache implementation

Question

Can mustache loop over a java Map? My object:

Map<Integer, String> mapTest

Tried this in my mustache template:

{{#mapTest}}
  {{.}}
{{/mapTest}}

That spits out a string representation (mapTest.toString()) of the entire object but doesn't loop at all.

import scala.collection.JavaConverters._
val myScalaMap = myJavaMap.asScala.mapValues(_.asScala.toSet)

I wouldn't hack the template to accommodate a Java object.
