IMO we should remove completly these 3 comments line.
**git** history and JIRA are here to remind us about it.
Could you please delete these lines?
> columnNames field of @Index annotation is ignored
> -------------------------------------------------
>
> Key: OPENJPA-223
> URL: https://issues.apache.org/jira/browse/OPENJPA-223
> Project: OpenJPA
> Issue Type: Bug
> Components: jdbc
> Affects Versions: 0.9.6
> Reporter: Marc Prud'hommeaux
> Priority: Major
>
> It looks like we completely ignore the "columnNames" field of the
> org.apache.openjpa.persistence.jdbc.Index annotation. From Jonathan Feinberg
> on the mailing list:
> Is there any way to cause the OpenJPA schema builder to emit an index across
> multiple columns? My attempt,
> @Column(columnDefinition = "bytea")
> @Index(name = "i_owner_md5", columnNames = { "owner_id, md5" })
> public byte[] getMd5()
> {
> return md5;
> }
> is silently misinterpreted, in that only the annotated field (md5) gets
> indexed.
