PlayFramework 2.4.6 error 413 Request Entity Too Large
<p>I am using PlayFramework 2.4.6, trying to upload a multipart file (size 18M) and the server returns the following error:</p>

<pre><code>For request 'POST /api/myEndpoint' [Request Entity Too Large]
</code></pre>

<p>I have looked around and tried the following with out success:</p>

<ol>
<li>play.http.parser.maxMemoryBuffer=2000000K</li>
<li>parsers.MultipartFormData.maxLength=1024000K</li>
<li>play.http.parser.maxDiskBuffer=2000000K</li>
<li>Action.async(parse.anyContent(Some(1024*200L)))</li>
</ol>

<p>And none of them solves the problem.</p>

<p>Here is the Stacktrace as well:</p>
