Norman Maurer 88481131be [#2353] Use a privileged block to get ClassLoader and System property if needed
Motivation:
When using System.getProperty(...) and various methods to get a ClassLoader it will fail when a SecurityManager is in place.

Modifications:
Use a priveled block if needed. This work is based in the PR #2353 done by @anilsaldhana .

Result:
Code works also when SecurityManager is present

* A HTTP server which serves Web Socket requests at:

* Open your browser at https://localhost:8081/, then the demo page will be loaded and a Web Socket connection will be

* This server illustrates support for the different web socket specification versions and will work with:
