* - 312503: JPA 2.0 CacheImpl behaviour change when recurse flag=false
* We only invalidate the subtree from the class parameter down when the recurse flag=false
* Previously only the class itself was invalidated
* The behaviour when the recurse flag is true is unaffected - the entire rooted (above) tree is invalidated
* Model must be extended to have subclasses of Small/LargeProject
* to verify semi-recursive functionality surrounding the equals() to isAssignableFrom() change
