--------------------------------------

Doesn't JIRA track when an issue is marked as a dupe? I had to do some legwork to find issue HHH-4601

> JPA 2 finally managed to fill the hole that @org.hibernate.annotations.Cascade(value=org.hibernate.annotations.CascadeType.DELETE_ORPHAN) was filling. Now @OneToMany has a (orphanRemoval = true) element - which should be trivial to implement in Hibernate 3.5 because it has exactly the same functionality as DELETE_ORPHAN.
> However, to my surprise, 3.5 Beta 2 does not implement that much desired feature/fix of JPA 2.
> The good news is that the corresponding @ManyToOne(optional = false) JPA 2 annotation seems to be working just dandy.
> I've attached a failing J2EE Web Application to demonstrate the failure. One might need to test across sessions to ensure that the DELETE_ORPHAN behaviour is as expected. The application is a modification of the NetBeans Web JPA Sample project and is set up to run on a Glassfish v3 server with Hibernate 3.5 installed via the Update Tool. (i.e. assumes Hibernate is installed on the J2EE server).
> To run the test, add an entry to the database through the web interface.
> You can uncomment the line in the Person entity class to use DELETE_ORPHAN and see that the test case passes when using the hibernate extension.
