If a region is specified as both an Entity region (class level) and a Collection region (on a @OneToMany association) then it will result in a ClassCastException on startup.
I originally used the same region name because I believed that they would pull from the same cache.
+Possible solution?+
_I believe that SessionFactoryImpl#determineCollectionRegionAccessStrategy should pull and cast from cacheAccessStrategiesMap as RegionAccessStrategy. Then check if the accessStrategy is an instanceof CollectionRegionAccessStrategy._
{code:java}
// shares a region with the collection cache
@Cache(region="com.test.EntityA")
public class EntityA {
}
public class EntityB {
// Shares a region
@Cache(region="com.test.EntityA")
public List<EntityA> getEntities() {
return entities;
}
}
{code}
