Workaround:
Specify the table:
@OneToMany( cascade=CascadeType.ALL )
@MapKeyEnumerated(EnumType.STRING)
@MapKeyColumn(table="ENUMKEYHOLDER_ENUMKEYPROPERTY", name="mymapkeycolulmn")
Map<MyEnum,EnumKeyProperty> properties = new HashMap<MyEnum,EnumKeyProperty>();
Possible fix:
OneToManyAccessor.processManyToManyMapping()
Move the processJoinTable call earlier in the method like this:
protected void processManyToManyMapping() {
// Create a M-M mapping and process common collection mapping metadata
// first followed by specific metadata.
ManyToManyMapping mapping = new ManyToManyMapping();
// Process the JoinTable metadata.
processJoinTable(mapping, mapping.getRelationTableMechanism(), getJoinTableMetadata());
process(mapping);
// 266912: If this 1:n accessor is different than the n:n mapping - track this
mapping.setDefinedAsOneToManyMapping(true);
}

At the moment, you need to specify the table name when using a map that uses a join table Given: @Entity public class EnumKeyHolder { @GeneratedValue @Id private int id; @OneToMany( cascade=CascadeType.ALL ) @MapKeyEnumerated(EnumType.STRING) @MapKeyColumn(name="mymapkeycolulmn") Map<MyEnum,EnumKeyProperty> properties = new HashMap<MyEnum,EnumKeyProperty>(); ... And public enum MyEnum{ VALUE1( "value1" ), // default VALUE2( "value2" ) ... @Entity public class EnumKeyProperty { @Id private int myKey; private int myValue; The following code will not put a value in the table for the map key: public static void main(String[] args) { EntityManagerFactory emf = Persistence.createEntityManagerFactory("TestEnumeratedMapKey"); EntityManager em = emf.createEntityManager(); em.getTransaction().begin(); EnumKeyHolder holder = new EnumKeyHolder(); EnumKeyProperty prop = new EnumKeyProperty(); prop.setMyKey(23); prop.setMyValue(22); holder.getProperties().put(MyEnum.VALUE1, prop); em.persist(holder); em.persist(prop); em.getTransaction().commit(); }
