This inspection checks for @ManyToMany associations with the CascadeType.REMOVE attribute. Specifying CascadeType.REMOVE for @ManyTOMany doesn’t make sense to be cascaded because it will propagate beyond the link table. Since the other side might be referenced by other entities on the parent-side, the automatic removal might end up in a ConstraintViolationException. For example, if @ManyToMany(cascade = CascadeType.ALL) was defined and the first person would be deleted, Hibernate would throw an exception because another person is still associated with the address that’s being deleted.
