Unable to Verify Sun Microsystems' (Bought over by Oracle) Java 6 Update 21 Plugin in Firefox 4.0 Beta 3 in Fedora 11 x86_64 64-bit Linux Operating System

Sun Aug 15 01:01:40 UTC 2010

My Fedora 11 Linux operating system is 64-bit (currently running 
standard Fedora kernel, NOT Xen pv-ops Dom0 kernel)
My Firefox 4.0 Beta 3 web browser (above Firefox 3.6.8 already) is 32-bit.
My Sun Java 6 Update 21 Plugin is also 32-bit.

In about:plugins in Firefox, I get:

    Java(TM) Plug-in 1.6.0_21

    File: libnpjp2.so
    Version: 
    The next generation Java <http://java.sun.com> plug-in for Mozilla
    browsers.

All properly installed.

But, when I go to verify Java version, by clicking on the following 
internet link:

http://www.java.com/en/download/installed.jsp

I get "Error. Click for details".

Here is the Java Console output detailing the error:

What's going on? And what's wrong?
