This error has nothing to do with using "" as a schema pattern. The
problem is that the server is supplying an ACL that the JDBC driver is
failing to parse correctly. So if these are the same databases, something
has changed in the 9.0 representation of privileges. I'm not sure what
that change might be. I've built a driver with the attached patch to show
the failing ACL. If you can provide the output on the failure, we can
likely fix it with little trouble.
