Golo can invoke public Java static methods by treating them as functions:

module sample

import java.util.Arrays

function oneTwoThree = {
  return asList(1, 2, 3)
}

In this example, asList is resolved from the java.util.Arrays import and called as a function. Note that we could equivalently have written a qualified invocation as Arrays.asList(1, 2, 3).
