Error executing JNLP file with Open Web Start

I have an old Applet that is using Java Web Start.
To launch this Applet, I use this JNLP file:

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" codebase="http://11.161.4.122:7777/aw_htm/">

    <param name="dontTruncateTabs" value="true"/>
  </applet-desc>
</jnlp>

I need to run the Applet with a technology that isn't obsolete or deprecated (yeah, I know I'm using an Applet, but my company has to mantain this product).
I've been recommanded to use Open Web Start, because it's still being mantained and updated and can, also, be an alternative to Java Web Start.
I installed it and I tried to run the JNLP file with it but I receive this error:

    ... 8 more

I run everything on Java 8.
Is it something in the configuration? Is Open Web Start not compatible with this JNLP or Applet?
