+++ This bug was initially created as a clone of Bug #1182303 +++

Description of problem:

@Entity
public class Product {
	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	private Long id;

	@OneToMany(mappedBy = "product", orphanRemoval = true)
	private List<Feature> features = new ArrayList<Feature>();
	...
}

@Entity
public class Feature { 
	@Id 
	@GeneratedValue(strategy=GenerationType.AUTO) 
	private Long id; 

	@ManyToOne() 
	private Product product;
	...
}

This affects EntityManager only. 

https://hibernate.atlassian.net/browse/HHH-9330

How reproducible: easy to reproduce.

Steps to Reproduce:
See the tests in org.hibernate.ejb.test.orphan.onetomany.DeleteOneToManyOrphansTest for details.

Actual results:
Clearing the collection of features in the Product will not result in deleting all Features of that product.

Expected results:
Features that were cleared should be deleted.

Additional info:

The workaround is setting the CascadeType.PERSIST in the Product entity.

Tests (which work properly) for Hibernate core are in org.hibernate.test.orphan.onetomany.DeleteOneToManyOrphansTest.

This was fixed in 4.2.17.Final.
