JDK-6675843 - Calls using new per-applet Packages keyword fail after page reload
Description
A request has been made on the java.net forum for access from JavaScript to static methods of an applet's classes, not just to the global Java namespace. This should be implementable in the new plug-in with syntax like

  myApplet.Packages.com.foo.Bar.baz()

assuming there is an applet on the page whose ID is "myApplet".

See http://forums.java.net/jive/thread.jspa?threadID=35072&tstart=0 for the original discussion.

SUGGESTED FIX http://sa.sfbay.sun.com/projects/deployment_data/6u10/6648488.0 testcase: http://j2se.east.sun.com/deployment/www/tests/1.6.0_10/6648488

EVALUATION Added support for the "Packages" keyword against the applet object, providing the necessary scoping to allow access to user-level classes including static fields, static methods and instantiation of new objects. The syntax looks like: applet1.Packages.com.company1.HelperClass.staticField or new applet1.Packages.com.company1.HelperClass() where "applet1" is the ID of the applet defined on the web page. The changes needed were to keep track of which object is the top-level object (i.e., the applet) exported to the web browser, and to inject support for the magic "Packages" keyword against only that object, returning a new top-level JavaNameSpace object for that field fetch. All of the other necessary infrastructure was already in place. Verified the new functionality both in IE and Firefox 3.
