    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42072#action_42072 ] 

Bouiaw commented on HHH-3008:
-----------------------------

Same issue for me with H2 and Hibernate 3.6.3.Final.
Even with updatable=true, it does not work.

>     @OneToMany(cascade = CascadeType.ALL)
>     @JoinTable(name = "owner_element",

> Attempting to delete an instance of Owner should also delete all associated instances of Element.  Instead I get the following error:
> SEVERE: Referential integrity constraint violation: FK56BBF9C487E817D: PUBLIC.OWNER_ELEMENT FOREIGN KEY(OWNER_ID) REFERENCES PUBLIC.OWNER(ID) [23003-63]
> This is because Hibernate attempts to delete the Owner row without first removing the rows from the join table.
