Comment 9 for bug 291135

I can confirm this. However, I am not sure this is fixed in Jaunty. I just installed sun-java6 from the jaunty repository, in my Intrepid box (it installs just fine). The problems with Java persisted (applets that used to work in Hardy were crashing firefox in Intrepid). A look into /etc/alternatives revealed that all the symlinks were pointing to the old location. For instance:

 xulrunner-javaplugin.so -> /usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7/libjavaplugin_oji.so

Symlinking everything pointing to libjavaplugin_oji.so into libnpjp2.so fixed my java issues:

cd /etc/alternatives/

sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so firefox-javaplugin.so
sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so iceape-javaplugin.so
sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so iceweasel-javaplugin.so
sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so midbrowser-javaplugin.so
sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so mozilla-javaplugin.so
sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so xulrunner-1.9-javaplugin.so
sudo ln -sf /usr/lib/jvm/java-6-sun/jre/lib/i386/libnpjp2.so xulrunner-javaplugin.so

Can this be fixed in both Intrepid and Jaunty? It seems to be a simple matter of correcting some symbolic links :-)

Many thanks!
