Given the following example, I generated DDL and no exception was given. I am trying to figure out what the default referenced column name for a join column is in this case, or in the case where one of the referenced column names is specified.

@Entity
@IdClass(EntityAIdClass.class)
public class EntityA {
    @Id
    private int id;

    @Id
    private int id2;
  
    @ElementCollection    
    @CollectionTable(name="EmbeddableType" ,  
            joinColumns={
                @JoinColumn(name="id"), 
                @JoinColumn(name="owningEntity")
            }
    )
    @MapKey(name="language") 
    private Map<String, EmbeddableType> embeddableTypes;
}

public class EntityAIdClass {
    private int id;
    private int id2;
}

@Embeddable
public class EmbeddableType {
    @Column(name="data") 
    private String data;

    @Column(name="language", nullable=false)
    private String language;
}
