[Building Sakai] 2.9.0 Realm/cache issue

[David Horwitz]

Hi All,

Testing our first take 2.9 installation I'm getting a weird class loader 
issue. This is triggered when a quartz job runs that updates a number of 
realms, basically a get from the cache fails due to the visibility of 
BaseRole. This is with 1.3.0-rc01 kernel, any one else seen this?
