Removing associated entity JPA (or delete orphan equivalent in EclipseLink)

I have a question regarding JPA persistence in Glassfish. Situation: I have a Supplier class that has a 1:n bidirectional relation to SupplierAddress. I would like to have the following behaviour: If I remove the SupplierAddress object from the List in the Supplier object and update it via the merge(supplierobject), the SupplierAddress tupel/object should be deleted. Is there an annotation do configure it like this or do I have to delete it manually. Any help would be very appreciated.

Greetings

Marcel

Not in JPA.

In Hibernate this is called "delete orphan". Since you work with EclipseLink, I found something like an equivalent:

@PrivateOwned - If you remove the reference to a target from a source, then delete the target.
