On PPC, 1.9.100-1 seems to be looking for /usr/lib/libgcj_fc4.so.6 instead of /usr/lib/libgcj.so.6 and hence all use of Java fails. A symlink makes it happy. I am unable to select /usr/lib/libgcj.so.6 from the configuration thingy for Java.
! wierd, because back when there was a libgcj_fc4.so.6 instead of libgcj.so.6 I had OOo patched to do that. But there is no such patch now in the spec, nor was that upstreamed. So there's no code which references libgcj_fc4.so.6 in OOo. Hmm... perhaps attach your ~/openoffice.org2.0/user/config/javasettings_Linux_*.xml file here, then rm it and restart OOo.
There should be no reason to touch the configuration thing for java unless debugging, or there are more than one javas installed and one is to be preferred over the other.

So would only affect someone who has ran the old ooo 1.9 previews which knew about libgcj_fc4
ah realistically I'm not going to go track this one down, only arose because of the short-term hack to get ooo working when libgcj_fc4.so.6 was in existance
