Hi Marcel,

your relationship is a uni-directional OneToMany, which must be annotated @OneToMany. Uni-directional OneToMany relationships are mapped to a join table by default. After commiting

tx.begin;
em.merge(garage);
em.commit;
tx.close

the join table entry should be removed from the database.
