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. For more info see the article.
