Hi, please forgive my english, but Im lost and I don't see if this is a bug or limitation, but I can't reuse a column ina ManyToMany association.
This is important because the schema is implemented and I need evaluate de migration.






public class Context {
	@Id String id;
	@Column name;
}

public class Group {
	@Id Context context;
	@Id String id;
	@Column name;
	@ManyToMany
	@JoinTable(
            joinColumns = {
            @JoinColumn(name = "context_id", referencedColumnName = "context_id"),
            @JoinColumn(name = "group_id", referencedColumnName = "id")},
            inverseJoinColumns = {
            @JoinColumn(name = "context_id", referencedColumnName = "context_id"),
            @JoinColumn(name = "role_id", referencedColumnName = "id")})
	Set<Role> roles;
	
}

public class Role {
	@Id Context context;
	@Id String id;
	@Column name;
}



Error: org.hibernate.MappingException: Repeated column in mapping for collection: test.Group.roles column: context_id
