Specifiying a HBM mapping with a many-to-many association with unique="true" triggers the generation of a unique constraint by Hibernate.
How to customize the unique constraint name in HBM mapping?
Whereas the many-to-one element seems to offer the unique-key attribute, this is missing from the many-to-many element.
So, is there a way to customize the unique constraint name for many-to-many association with unique="true" ?

Thanks,
Holger
