I created an CDO server config that has branching disabled. Then I tried connecting using the CDO repositories view. The connection is established. When I expand the repository node in the view, I got the following exception: 

java.lang.UnsupportedOperationException: Mapping strategy does not support branching

Reproducible: Always

Steps to Reproduce:
1. start CDO server with no branching.
2. connect using CDO Repositories view.
3. expand repository node in view.
