A many-to-many association always needs a join table. A join column is not sufficient: it only enables a one-to-many association.
If you don’t specify any
@JoinTableannotation on the association, then default values will be used. Hibernate wil use a join table with a default name and default columns composed from the names and IDs of the associated entities.
