I really dont get how people extract "bug" from something that is explicitly documented to not happen that way.

>             Project: Hibernate Core
>          Issue Type: New Feature
>          Components: entity-manager
>    Affects Versions: 3.3.2, 3.5.5, 3.6.0.Beta4
>         Environment: Hibernate 3.5.x, all database, all platforms.

> I have an entity with a collection of basic elements mapped with @ElementCollection:
> {code}
> @Entity
> public class Foo {
>     @Id @GeneratedValue
>     private Long id;
>     @ElementCollection
>     @Column(name = "bar_column")
>     @CollectionTable(name = "Bar")
>     private Set<String> bars = new HashSet<String>();
>     public Long getId() { return id; }
>     public void setId(Long id) { this.id = id; }
>     public Set<String> getBars() { return bars; }
>     public void setBars(Set<String> bars) { this.bars = bars; }
> }
> {code}
> A bulk delete on this entity fails due to constraint violation on the collection table (Hibernate ignores the collection table).
> I don't think that the following cascading restriction from the JPA 2.0 specification applies:
> {quote}
> h3. 4.10 Bulk Update and Delete Operations
> ...
> A delete operation only applies to entities of the specified class and its subclasses. It does not cascade to related entities.
> {quote}
> In other words, Hibernate should handle the collection table as we have no way to bulk delete the basic elements from the collection table.
> I have attached a test case allowing to reproduce the issue.
