We need a fix for Hibernate issue HHH-4257

Issue

• I've got a collection of elements.  Both the key and value in this case are enum classes.  The key seems to be the problem here.  The first error I get is that getBytes() cannot be applied to an integer field (the db schema has an integer, as was used in previous versions of Hibernate).

  @CollectionOfElements(fetch = FetchType.EAGER)
  private Map<SomeEnum, SomeOtherEnum> someMap;
