Can you provide more details? How is your class mapped? Can you provide a snippet of your code?

public class User {

    @Id
    @Column(name = "cid")
    private String id;
}

public class Role {

    @Id
    @Column(name = "cid")
    private String id;
}

public class UserRole {

    @Id
    @PrimaryKeyJoinColumn(name = "cuserid")
    private User user;

    @Id
    @PrimaryKeyJoinColumn(name = "croleid")
    private Role role;
}

In this case EclipseLink assumes:

cuserid column name as USER.cid
croleid column name as ROLE.cid

Hope helps.

A derived id mapping should use JoinColumn and not PrimaryKeyJoinColumn.

Targeting as P4 future. Eclipselink could log a warning in this case.
