Oops, sorry for multiple posts. To clarify, looks like the libjavaplugin.so version is somehow broken (or has an incorrect name; I remember some forum post about similar issues where they'd had to rename libjavaplugin.so to something else). I didn't need *both* the entries, only to replace libjavaplugin.so with libjpnp2.so (just re-checked by removing the libjavaplugin.so symlinks).
And, to be crystal clear, the original symlinks were indirect, via /etc/alternatives/firefox-javaplugin.so and /etc/alternatives/mozilla-javaplugin.so (just in case anyone else is trying to reproduce my 'fix').
