/**
 * Unit test for:
 *
 *  https://glassfish.dev.java.net/issues/show_bug.cgi?id=4407
 *  ("After changing the port of an http listener the mapped webapps of
 *  virtual servers get lost")
 *
 * This unit test does the following:
 *
 * - Creates virtual server myvs, and associates it with http-listener-1
 * - Deploys webapp to myvs, and assigns this webapp as the default-web-module
 *   of myvs
 * - Modifies the port of http-listener-1
 * - Accesses the webapp deployed on myvs at the new port. The webapp is
 *   accessed both at its regular context root, as well as at the root context
 *   of myvs
