A DESCRIPTION OF THE PROBLEM :
Starting from JDK 6u101 Classic (old) Java Plugin does not function in Internet Explorer (IE) browser. Loading of a web page containing an applet in IE, when the Next-Generation Java Plugin is disabled, does not lead to loading of the applet with the classic plugin, and the web page is displayed without any indication that it contains the applet.

1. Uninstall all JREs from the host.
2. Install JRE 6 which will be tested.
3. Go to "Java Control Panel -> Advanced.
    3.1. Set "Java console" to "Show console", click "Apply".
    3.2. Switch off the next option in "Java Plug-in" group:
        - "Enable the next-generation Java Plug-in (requires browser restart)"
    3.3. Click "Disable" in the raised security warning dialog.
    3.4. Click "OK" and agree with all questions in the further raised dialogs.
4. Launch IE browser and load a web page with any applet which is compatible with JDK 6. For example, the next URL of the web page with "HelloWorld" applet from The Java Tutorials web site.
    URL: http://docs.oracle.com/javase/tutorial/deployment/applet/getStarted.html
5. The bug is reproduced, if "HelloWorld" applet is not displayed on the page and Java Console is not shown.
