title: Authentication required pop-up when loading JNLP for internal website
body: <p>Recently we started to upgrade our clients from Java 6u31 to 8u121.</p>
  
  <p>Here we see an impact on our internal web application written in Java.</p>
  
  <p>Client(s) connects to a web-server which has the JNLP and JARs locally.</p>
  
  <p>However now with the new Java 8u121 we get a pop-up from java : Authentication required.
  We can click on cancel and the Java app will load but this is not acceptable for our users.</p>
  
  <p>Is this a Java problem or a Proxy problem?</p>
