When a PersistentCollection of primitives like String.class are persisted, if
the collection is marked as eager fetching. An exception is thrown upon loading
the collection :
Attached is a patch file to the 2.0.0 trunk's junit test which illustrates the
collection working with lazy and failing with eager. This also happens in 1.2.1
