I've created a brand new Platform Application, then a module, and the a Java class in the module. The header in the file says:

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

1. There is no "License Headers" in the Project Properties.
2. I went to the Tools | Templates. First I checked "Module Development" templates, but I cannot edit any of them, and there is no template for Java class. So I opened the regular template for a Java Class, and what am I supposed to do there:

<#assign licenseFirst = "/*">
<#assign licensePrefix = " * ">
<#assign licenseLast = " */">
<#include "${project.licensePath}">

How to change the header text? How to change the license? Where the ${project.licensePath} comes from in a platform module?
