Is browser plugin broken?

[Mikhail T.]

Hello!

I'm trying to enable Java plugin on my FreeBSD-8.2/amd64 machine -- 
fruitlessly. Though Java (installed by the java/jdk16 port) itself is 
working great (vuze and serviio are running 24/7), Firefox (6.0.2) does 
not open any applets -- and, most annoyingly, does not output any 
diagnostics either.

There are several recipes out there, some talk about sym-linking 
libjavaplugin_jni.so into various directories and others -- about 
changing the java.* configuration strings in Firefox' about:config.

The authoritative manual, however, refers to OpenJDK:

    http://www.freebsd.org/doc/handbook/desktop-browsers.html#MOZ-JAVA-PLUGIN

-- is there something broken in jdk16, that makes it unusable with 
Firefox? Thanks!
