actually I switched to a debian repository some time ago.
the last thing I remember fiddling with was the X settings.
could the non-gij javas have had problems connecting to the X server?
I don't have the xorg.conf any longer.
sorry if this doesn't help. but I guess this bug should to be closed.
oobase still gives the errors described with the following packages:
java-common 0.25ubuntu1
libhsqldb-java 1.8.0.5-2ubuntu1
