This is trying to use the plugin from Java 1.4.2 unless the one linked
to /etc/alternatives/mozilla-javaplugin.so (which I've never seen) is
a 1.5 plugin.  Is 1.4.2 still installed on your machine?

If 1.4.2 isn't still installed on your computer, it's trying to use a
plugin from a runtime that no longer exists.  Find your current java
install location (where 1.5 is installed), then make a new symlink to
it from your /usr/lib/mozilla/plugins directory.  (You may also want
to make a symlink to it from your .mozilla/plugins directory in your
home directory.

This is what I have done on my own system.  Anyone else feel free to
correct me if I'm wrong.
