I installed Appian 7.10 no problem but had to roll back to 7.9 to be consistent

I installed Appian 7.10 no problem but had to roll back to 7.9 to be consistent with a client version used.
Have kept the following the same:

- MySQL - just dropped and recreated my appian_primary db so that it would recreate schemas
- JBOSS 6.4 EAP - no changes
- JDK 1.8_60 - no changes
- Appian - refreshed licence, custom.properties, appian-topology.properties files etc.

Tried with 7.9 + Hotfix D AND plain 7.9 vanilla....both start up with the following:

"Error 403 Forbidden, Sorry your request could not be processed"

The stack trace looks like:
