This semantics of implied deletion of elements from the database as they
are removed from their collection in Java memory is supported by
@ElementDependent annotation (not pure JPA but OpenJPA)

Subject: Implied deletes

Does OPEN-JPA support implied deletes? Let me tell you of the scenario;
if you have the proverbial magazine class that contains references to
several article classes (1-* relationship, cascade-all) if you should
remove one of the articles from the contained list and merge the
resultant magazine class will the removed article class be automatically
deleted?
The alternative would be to remove the article class and delete it
manually then merge the magazine class.
