Typesafe activator 1.3.9 no longer works (regarless of the version)
<p>Just downloaded and installed <code>activator</code> 1.3.9 for Play-Scala 2.3.8 on a new fresh Ubuntu 15.10 box (jdk 8, scala 2.11.6 were already installed).</p>

<p>The problem is that the <code>activator</code> no longer works and I always get the following errors (even with the latest version of the <code>activator</code>):</p>

<pre><code>j3d@gonzo:~$ activator
