[Building Sakai] 2.9.0 Realm/cache issue

[Matthew Jones]

I haven't seen it yet, but the line is related to the new authz caching.

https://jira.sakaiproject.org/browse/KNL-600

I'm not completely sure the fix, but perhaps it needs to put Role objects
(which are in a shared api) instead of BaseRole.
