Does JPA (and EclipseLink, as its reference implementation) support...derived many-to-one relationships?

I wonder, could I abuse the "table" attribute of the @JoinColumn annotation?

public class Response {
  @ManyToOne
  @JoinColumns({
    @JoinColumn(name = "answerID"), // straightforward
    @JoinColumn(table = "NamedAnswerSet", name = "name") // guessing this won't cut it
  })
  private Answer answer;
}

Best,
