--------------------------

             Summary: TreeImpl#NodeLocation does not allow to retrieve child location if access to parent is denied
                 Key: OAK-766
                 URL: https://issues.apache.org/jira/browse/OAK-766
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core
            Reporter: angela


as a consequence of OAK-709 we now have an issue with the way
SessionDelegate and Root#getLocation access a node in the hierarchy
which has an ancestor which is not accessible.

specifically RootImpl#getLocation will be served a NullLocation for the
first ancestor which is not accessible and consequently any accessible
child node cannot be accessed.

in order to reproduce the issue you may:

- change AccessControlConfigurationImpl to use PermissionProviderImpl instead
  of the tmp solution
- and run o.a.j.oak.jcr.security.authorization.ReadTest#testReadDenied
