Comment 5 for bug 66621

No the link doesn't exist even after configuring it again.

Here is what I did:
sudo update-alternatives --config firefox-javaplugin.so
Password:

There are 2 alternatives which provide `firefox-javaplugin.so'.

  Selection Alternative
-----------------------------------------------
 + 1 /usr/lib/jvm/java-gcj/jre/lib/libgcjwebplugin.so
          2 /usr/lib/gcj-4.1/libgcjwebplugin.so

Press enter to keep the default[*], or type selection number: 1
Using `/usr/lib/jvm/java-gcj/jre/lib/libgcjwebplugin.so' to provide `firefox-javaplugin.so'.

Even after this the link is not created.
