When starting server, using ModeShape as repo, error - Supertype 'nt:hierarchyNode' from type 'drools:configurationNodeType' does not exist

When starting the server, when ModeShape is used as the repo, the following error is seen in the log:

2011-06-29 12:48:32,553 ERROR [org.modeshape.jcr.RepositoryNodeTypeManager] (modeshape-start-repo-2-thread-1) Node types were read from the system content, and appear to be inconsistent or invalid: org.modeshape.jcr.nodetype.InvalidNodeTypeDefinitionException: Supertype 'nt:hierarchyNode' from type 'drools:configurationNodeType' does not exist

Restarted server after deleting the default/data/modeshape directory, and still see the error.
