Version 18.104.22.168 is the terminal release for version 8. Oracle will only gurantee that patches will work for this version. The patches are not tested against earlier versions. The problems described in Alert #68 were probably in the original 8.0.1 release, and not caught before this time. There is no way to tell if an earlier patched caused one of these problems. You MUST upgrade to 22.214.171.124 BEFORE applying the security patches.
