I have upgraded Ubuntu 7.10 to 8.04 in the dev branch some things aren't working. I installed the latest openoffice from OpenOffice.org and it wouldn't install using the provided java installer and when I installed it using the deb download it couldn't find Java.

Further investigation showed that java wouldn't run at all (see the error below).

I googled and found a related problem and Java Fix for Ubuntu 8.04 Java not running problem

Update: The above fix will not work for the Openoffice setup program which includes it's own jre which is unpacked and the same error occurs. The work around for this is create a file named runsetup or similar with the following in it.

export LIBXCB_ALLOW_SLOPPY_LOCK=true
./setup

and then
sudo sh ./runsetup

and then the installer will work.
