committed
actually fix up the unsafe methods of JpaMetamodel
this change exposed multiple bugs! 1. generic attributes declared by a mapped superclass where not being handled properly in HQL path expressions 2. getSubTypes() on EntityTypeImpl was broken (due, again, to use of unchecked cast!) causing problems in HQL
