Implementation of jnlp://

[Nicolas Roduit]

In my opinion this feature is major against the slow death of the Java 
client side although its implementation is very simple. It offers the 
possibility to launch an application from many contexts (browsers, mail 
client...).

For some advanced applications, we still believe that running a Java 
client application is the good choice (easy deployment, performance, 
maintainability).

However, since  JRE 8_121  I'm disappointed about the security behaviors 
of JWS. I've filled out a bug at 
https://bugs.openjdk.java.net/browse/JDK-8175981 but the guys from 
Oracle consider as a "security" feature.  As I don't have the permission 
to post a comment, I can only think that Oracle is killing the dynamic 
behavior of JWS. Hopefully, this issue doesn't appear with the new jnlp 
protocol.

I've seen that the version 1.7 will have a windows experimental version. 
It would be nice if a future version of the IcedTea-web could install 
the mechanism for the jnlp handler (on Windows it is very simple).

Best,

Nicolas
