Comment 7 for bug 190214

There are several areas in OOo that warn to install that package but it can't warn in every spot that uses Java. Pretty much you need to have openoffice.org-java-common installed at minimum if you do much of anything in OOo, and perferably the 'openoffice.org' package as well which pulls most everything else in. Unfortunately neither of those packages will fit on the Ubuntu CD which is why they aren't installed by default.
