I've just run into this problem again and am posting back here so I don't forget again. 

When trying to delete an entity that has existing relationships (eg. OneToMany) you have to ensure that you clear the collection before removing the object. eg:public void deleteGroup(Group group) {
  | 
  | 	//where the relationship btw a 'User' and a 'Group' is maintained in a 'UserGroupList'
  | 
  | 	group.getUserGroupLists().clear();
  | 	entityManager.remove(group);
  | }
Cheers,

Damian.
